iwlwifi: fix fw_pre_next_step to apply also for C step

Browse source 
C step NICs should use the latest FW (currently B step).
Correct the condition to make C step NICs advanced its default FW name
to the latest one.
Also rename _next_ to b_or_c to avoid confusion.

Fixes: 5da083d192 ("iwlwifi: add support for 9000 HW B-step NICs")
