afs: Return -EAGAIN, not -EREMOTEIO, when a file already locked
[ Upstream commit 0066f1b0e27556381402db3ff31f85d2a2265858 ]
When trying to get a file lock on an AFS file, the server may return
UAEAGAIN to indicate that the lock is already held. This is currently
translated by the default path to -EREMOTEIO.
Translate it instead to -EAGAIN so that we know we can retry it.
