CHROMIUM: fix a ChromiumOS-specific memory leak in fs/namei.c

CL:334279 added a pair of functions in fs/namei.c:
nameidata_set_temporary() and nameidata_restore_temporary().
The first of these two functions allocates a new "struct nameidata" and
also a "struct filename" which gets assigned in nameidata->name.
nameidata_restore_temporary() frees nameidata, but forgets to free
the "->name" reference, which leads to the leak of that "struct

This change makes nameidata_restore_temporary() dereference
nameidata->name before freeing the temporary nameidata.
