xfs: don't use __GFP_NOFAIL in xfs_init_fs_context

Browse source 
With enough debug options enabled, struct xfs_mount is larger
than 4k and thus NOFAIL allocations won't work for it.

xfs_init_fs_context is early in the mount process, and if we really
are out of memory there we'd better give up ASAP anyway.

Fixes: 7b77b46a61 ("xfs: use kmem functions for struct xfs_mount")
