bnxt_en: Fix trimming of P5 RX and TX rings

Browse source

The recent commit to trim the RX and TX rings on P5 chips by assigning
each with max CP rings divided by 2 is not correct.  Max CP rings
divided by 2 may be bigger than the original RX or TX and would
lead to failure.  In other words, we may be checking for increased
RX/TX rings than required and it may fail.

Fix it by calling __bnxt_trim_rings() instead that would properly
trim RX and TX without the possibility of increasing their values.

Fixes: f5b29c6afe ("bnxt_en: Add helper to get the number of CP rings required for TX rings")
