bnxt_en: Add bnxt_setup_ctxm_pg_tbls() helper function

In bnxt_alloc_ctx_mem(), the logic to set up the context memory entries
and to allocate the context memory tables is done repetitively.  Add
a helper function to simplify the code.

The setup of the Fast Path TQM entries relies on some information from
the Slow Path TQM entries.  Copy the SP_TQM entries to the FP_TQM
entries to simplify the logic.
