NFS: Fix the mapping of the NFSERR_SERVERFAULT error
It was recently pointed out that the NFSERR_SERVERFAULT error, which is
designed to inform the user of a serious internal error on the server, was
being mapped to an error value that is internal to the kernel.
This patch maps it to the error EREMOTEIO, which is exported to userland
through errno.h.

NFS: Fix a bug in nfs_fscache_release_page()
Not having an fscache cookie is perfectly valid if the user didn't mount
with the fscache option.
