[PATCH net] bnxt: fix memory leak in bnxt_queue_mem_alloc error cases

[Will Chen]

There is a small memory leak in bnxt_queue_mem_alloc:
when bnxt_alloc_rx_agg_bmap() succeeds
but bnxt_alloc_one_tpa_info() later fails,
the rx_agg_bmap allocated by bnxt_alloc_rx_agg_bmap()
is not freed in the fallthrough cleanup cases.

Simply free the rx_agg_bmap in the err_free_tpa_info case,
as this is the only remaining error path where
rx_agg_bmap is allocated and needs to be freed.

Fixes: bd649c5cc958 ("bnxt_en: handle tpa_info in queue API implementation")
