bnxt_en: Improve bnxt_backing_store_cfg_v2()
Improve the logic that determines the last_type in this function.
The different context memory types are configured in a loop. The
last_type signals the last context memory type to be configured
which requires the ALL_DONE flag to be set for the FW.
The existing logic makes some assumptions that TIM is the last_type
when RDMA is enabled or FTQM is the last_type when only L2 is
enabled. Improve it to just search for the last_type so that we
don't need to make these assumptions that won't necessary be true
for future devices.
