scsi: lpfc: Separate NVMET RQ buffer posting from IO resources SGL/iocbq/context
Currently IO resources are mapped 1 to 1 with RQ buffers posted
Added logic to separate RQE buffers from IO op resources
(sgl/iocbq/context). During initialization, the driver will determine
how many SGLs it will allocate for NVMET (based on what the firmware
reports) and associate a NVMET IOCBq and NVMET context structure with
each one.
Now that hdr/data buffers are immediately reposted back to the RQ, 512
RQEs for each MRQ is sufficient. Also, since NVMET data buffers are now
128 bytes, lpfc_nvmet_mrq_post is not necessary anymore as we will
always post the max (512) buffers per NVMET MRQ.
