drbd: rename "usermode_helper" to "drbd_usermode_helper" 

Nothing like having a very generic global variable in a tiny driver
subsystem to make a mess of the global namespace...

Note, there are many other "generic" named global variables in the drbd
subsystem, someone should fix those up one day before they hit a linking
error.
