Patch from Robert Love <rml@tech9.net>

This patch is by Inaky Perez-Gonzalez.

There are a couple uses of 'p->state=foo' in fs/ which are open coded. 
This patch converts them to the proper [__]set_current_state() function.

At least one of them (the one fs/locks.c usage) is probably unsafe on
out-of-order store processors.  This patch fixes it up.
