RDMA/bnxt_re: Fix incorrect display of inactivity_cp in debugfs output

The inactivity_cp parameter in debugfs was not being read or
written correctly, resulting in "Invalid argument" errors.

Fixed this by ensuring proper mapping of inactivity_cp in
both the map_cc_config_offset_gen0_ext0 and
bnxt_re_fill_gen0_ext0() functions.
