scsi: lpfc: Fix list corruption detected in lpfc_put_sgl_per_hdwq
In lpfc_release_io_buf, an lpfc_io_buf is returned to the 'available' pool
before any associated sgl or cmd and rsp buffers are returned via their
respective 'put' routines. If xri rebalancing occurs and an lpfc_io_buf
structure is reused quickly, there may be a race condition between release
of old and association of new resources.
Re-ordered lpfc_release_io_buf to release sgl and cmd/rsp
buffer lists before releasing the lpfc_io_buf structure for re-use.
Fixes: d79c9e9d4b3d ("scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware.")
