drm: remove master fd restriction on mode setting getters

Browse source 
Its useful to be able to call the mode setting getter ioctls.
Not requiring master fd, enables writing a simple program which
can query the state of the video system.

Since these ioctls are only "getters" there is no security or
synchronization issues which would require master fd. Opening
an new fd is already protected by the file permissions on the
device file.
