scsi: hisi_sas: Flush workqueue in hisi_sas_v3_remove()
If the controller reset occurs at the same time as driver removal, it may
be possible that the interrupts have been released prior to the host
softreset, and calling pci_irq_vector() there causes a WARN:
WARNING: CPU: 37 PID: 1542 /pci/msi.c:1275 pci_irq_vector+0xc0/0xd0
Call trace:
pci_irq_vector+0xc0/0xd0
disable_host_v3_hw+0x58/0x5b0 [hisi_sas_v3_hw]
soft_reset_v3_hw+0x40/0xc0 [hisi_sas_v3_hw]
hisi_sas_controller_reset+0x150/0x260 [hisi_sas_main]
hisi_sas_rst_work_handler+0x3c/0x58 [hisi_sas_main]
To fix, flush the driver workqueue prior to releasing the interrupts to
ensure any resets have been completed.
