Abort code UAEOVERFLOW is returned when we try and set a time that's out of
range, but it's currently mapped to EREMOTEIO by the default case.
Fix UAEOVERFLOW to map instead to EOVERFLOW.
Found with the generic/258 xfstest. Note that the test is wrong as it
assumes that the filesystem will support a pre-UNIX-epoch date.
Fixes: 1eda8bab70 ("afs: Add support for the UAE error table")
