[syslog-ng] [PATCH] afsql: Fix a deadlock when using explicit commits.

[Gergely Nagy]

When using explicit commits, in case the COMMIT results in an error,
syslog-ng forgot to release a mutex, resulting in a deadlock the next
time the same error happened.

The fix is to do release the mutex in this error path, too.
