[ 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.
