Subject: scsi: qla2xxx: Initialize Work element before requesting IRQs

From: Himanshu Madhani <[email protected]>

commit 1010f21ecf8ac43be676d498742de18fa6c20987 upstream.

commit a9e170e28636 ("scsi: qla2xxx: Fix uninitialized work element") moved initializiation of work element earlier in the probe to fix call stack. However, it still leaves a window where interrupt can be generated before work element is initialized. Fix that window by initializing work element before we are requesting IRQs.

[mkp: fixed typos]
