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'
directly.
