megaraid_sas: online Firmware upgrade support for Extended VD feature

Browse Source 
In OCR (Online Controller Reset) path, driver sets adapter state to
MEGASAS_HBA_OPERATIONAL before getting new RAID map.  There will be a small
window where IO will come from OS with old RAID map.  This patch will
update adapter state to MEGASAS_HBA_OPERATIONAL, only after driver has new
RAID map to avoid any IOs getting build using old RAID map.
