scsi: bfa: fix type conversion warning
A regression fix introduced a harmless type mismatch warning:
drivers/scsi/bfa/bfad_bsg.c: In function 'bfad_im_bsg_vendor_request':
drivers/scsi/bfa/bfad_bsg.c:3137:35: error: initialization of 'struct bfad_im_port_s *' from 'long unsigned int' makes pointer from integer without a cast [-Werror=int-conversion]
struct bfad_im_port_s *im_port = shost->hostdata[0];
^~~~~
drivers/scsi/bfa/bfad_bsg.c: In function 'bfad_im_bsg_els_ct_request':
drivers/scsi/bfa/bfad_bsg.c:3353:35: error: initialization of 'struct bfad_im_port_s *' from 'long unsigned int' makes pointer from integer without a cast [-Werror=int-conversion]
struct bfad_im_port_s *im_port = shost->hostdata[0];
This changes the code back to shost_priv() once more, but encapsulates
it in an inline function to document the rather unusual way of
using the private data only as a pointer to the previously allocated
structure.
I did not try to get rid of the extra indirection level entirely,
which would have been rather invasive and required reworking the entire
initialization sequence.
