scsi: Improve scsi_get_sense_info_fld

Use get_unaligned_be32 and get_unaligned_be64 to obtain values from the
sense buffer instead of open coding the operations.  Also change the
function return value to a bool and fix the function signature
declaration to remove spaces triggering checkpatch warnings.

No functional change is introduced by this patch.
