Log Message:
kern_descrip.c: Change membar_enter to membar_acquire in fd_getfile.
membar_acquire is cheaper on many CPUs, and unlikely to be costlier
on any CPUs, than the legacy membar_enter.
Add a long comment explaining the interaction between fd_getfile and
fd_close and why membar_acquire is safe.
