scsi: qedi: Fix error return code of qedi_alloc_global_queues()

BugLink: https://bugs.launchpad.net/bugs/1923220
[ Upstream commit f69953837ca5d98aa983a138dc0b90a411e9c763 ]

When kzalloc() returns NULL to qedi->global_queues[i], no error return code
of qedi_alloc_global_queues() is assigned.  To fix this bug, status is
assigned with -ENOMEM in this case.
