fbmem: Remove mutex use from do_fb_ioctl()



Remove use of this mutex to allow multiple msm_fb ioctl calls.
Mutexes within the individual fb_ioctl calls already provide
the necessary locking.

This is based on android-msm-2.6.35 commit:
a809819d (msm_fb: display: Add delay kickoff to MDDI)
which includes this change among others.
