[GFS2] fix GFP_KERNEL misuses
There are several places where GFP_KERNEL allocations happen under a glock,
which will result in hangs if we're under memory pressure and go to re-enter the
fs in order to flush stuff out. This patch changes the culprits to GFS_NOFS to
keep this problem from happening. Thank you,
