scsi: qla2xxx: Fix device reconnect in loop topology
commit 8ad4be3d15cf144b5834bdb00d5bbe4050938dc7 upstream.
A device logout in loop topology initiates a device connection teardown
which loses the FW device handle. In loop topo, the device handle is not
regrabbed leading to device login failures and eventually to loss of the
device. Fix this by taking the main login path that does it.
