Andreas Gruenbacher 5e43db2d8c gfs2: Silence "suspicious RCU usage in gfs2_permission" warning 
[ Upstream commit 074d7306a4fe22fcac0b53f699f92757ab1cee99 ]

Commit 0abd1557e21c added rcu_dereference() for dereferencing ip->i_gl
in gfs2_permission.  This now causes lockdep to complain when
gfs2_permission is called in non-RCU context:

    WARNING: suspicious RCU usage in gfs2_permission

Switch to rcu_dereference_check() and check for the MAY_NOT_BLOCK flag
to shut up lockdep when we know that dereferencing ip->i_gl is safe.

Fixes: 0abd1557e21c ("gfs2: fix an oops in gfs2_permission")
