The 'cmdq->cmdq_bitmap' bitmap is 'rcfw->cmdq_depth' bits long. The size
stored in 'cmdq->bmap_size' is the size of the bitmap in bytes.
Remove this erroneous 'bmap_size' and use 'rcfw->cmdq_depth' directly in
'bnxt_qplib_disable_rcfw_channel()'. Otherwise some error messages may be
missing.
Other uses of 'cmdq_bitmap' already take into account 'rcfw->cmdq_depth'
