scsi: 3w-xxxx: Add error handling for initialization failure in tw_probe()

Smatch complains that:

tw_probe() warn: missing error code 'retval'

This patch adds error checking to tw_probe() to handle initialization
failure. If tw_reset_sequence() function returns a non-zero value, the
function will return -EINVAL to indicate initialization failure.
