Andreas Gruenbacher be020f658c gfs2: Silence "suspicious RCU usage in gfs2_permission" warning
[ Upstream commit 074d7306a4 ]

Commit 0abd1557e2 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.
