Newer firmware advertises the number of TQM rings to allocate
context memory for.  Use the firmware specified value and fall back
to the old value derived from "bp->max_q" if it is not available.

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

The current formulas to calculate the TQM slow path and fast path ring
context memory sizes are not quite correct. TQM slow path entry is
array index 0 of ctx->tqm_mem[]. The other array entries are for fast
path. Fix these sizes according to firmware spec. for 57500 and newer
chips.
