[PATCH] nfsd: don't use GFP_KERNEL from nfsd_getxattr()/nfsd_listxattr()

[Tetsuo Handa <penguin-kernel@xxxxxxxxxxxxxxxxxxx>]

Since GFP_KERNEL is GFP_NOFS | __GFP_FS, usage like GFP_KERNEL | GFP_NOFS
does not make sense. Drop __GFP_FS flag in order to avoid deadlock.

Fixes: 32119446bb65 ("nfsd: define xattr functions to call into their vfs counterparts")
