Liam R. Howlett 27b2670112 ipc/shm: introduce new do_vma_munmap() to munmap
The shm already has the vma iterator in position for a write. 
do_vmi_munmap() searches for the correct position and aligns the write, so
it is not the right function to use in this case.

The shm VMA tree modification is similar to the brk munmap situation, the
vma iterator is in position and the VMA is already known.  This patch
generalizes the brk munmap function do_brk_munmap() to be used for any
other callers with the vma iterator already in position to munmap a VMA.
