Miscellaneous Fixes and Corrections
- Remove the memset in the lpfc_sli4_remove_rpi_hdrs call.
- Correct swapping of SGE word 2 relative to offset value
- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
  is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
  then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
  PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
  instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
  reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override
  with 0x80000000.
- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
  unregistering the fcf if Devloss fires before Delay discover timer fires.
