VFS: Add LOOKUP_SHARED flag.
Some ->lookup handlers will need to drop and retake the parent lock, so
they can safely use d_alloc_parallel().
->lookup can be called with the parent lock either exclusive or shared.
A new flag, LOOKUP_SHARED, tells ->lookup how the parent is locked.
This is rather ugly, but will be gone soon after we move
d_alloc_parallel() out of the directory lock as ->lookup() will *always*
called with a shared lock on the parent.
