scsi: qla2xxx: Initialize variable in qla8044_poll_reg()

Browse Source 
clang static analysis reports this problem:

qla_nx2.c:694:3: warning: 6th function call argument is
  an uninitialized value
        ql_log(ql_log_fatal, vha, 0xb090,
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In qla8044_poll_reg(), when reading the reg fails, the error is reported by
reusing the timeout error reporter.  Because the value is unset, a garbage
value will be reported.  Initialize the value.
