cifs: helper function to check replayable error codes

Browse source 
[ Upstream commit 64cc377b76 ]

The code to check for replay is not just -EAGAIN. In some
cases, the send request or receive response may result in
network errors, which we're now mapping to -ECONNABORTED.

This change introduces a helper function which checks
if the error returned in one of the above two errors.
And all checks for replays will now use this helper.
