bnxt_en: Use firmware provided maximum filter counts.

While individual filter structures are allocated as needed, there is an
array to keep track of the software filter IDs that we allocate ahead
of time.  Rather than relying on a fixed maximum filter count to
allocate this array, get the maximum from the firmware when available.

Move these filter related maximum counts queried from the firmware to the
bnxt_hw_resc struct.  If the firmware is not providing these maximum
counts, fall back to the hard-coded constant.
