[SCSI] bfa: Replace bfa_get_attr() with specific APIs
bfa_ioc_attr_s is a big structure and some times could cause stack overflow if defined locally, so add specific APIs that are needed to replace the use of ioc_attr local var. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
