This patch removes if conditions with no exececutable
statements in the bodies of those ifs and also no variable
assignments in the if conditional checks. The call to
rtllib_act_scanning in the condition doesn't have any side
effects as it too performs conditional checks without changing
any values. Hence, it's safe to remove the if condition.

Removes extra parentheses around bitwise right shift operation.
The cases handled are when the resultant value is assigned to
a variable or when a shift operation is carried out for a function
argument. The issues were detected and resolved using the following

constant c;

rtllib_association_req is a (large) inline function which defines 2 constant
static arrays which aren't labelled as const. As a result clang complains with:
non-constant static local variable in inline function may be different in
different files
[-Wstatic-local-in-inline]
static u8 AironetIeOui[] = {0x00, 0x01, 0x66};
^
The solution is making them "static const".
However doing so requires dropping const when being used with struct
octet_string. However the value is used in a const fashion thereafter, so no
harm done.

MgntQuery_MgntFrameTxRate is only used within rtllib_softmac.c, so it really
should be static instead of extern.
Since it is currently extern a warning is generated because a different
function of the same name is defined staticlly in ieee80211_softmac.c
Removing the incorrect extern declaration and defining the rtllib_softmac
version of this routine static fixes the warning.

With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the opposite thing from older versions of gcc
(emits code for an externally linkable version of the inline function).
"static inline" does the intended behavior in all cases instead.
