net/bnxt: fix L2 context calculation for Thor

Browse Source 
On Wh+, number of L2 context supported by FW is the sum of number of
EM flow count and number of L2 context count returned in HWRM_FUNC_QCFG.
This is not true for Thor. Restrict this only for Whitney for now.

Fixes: ff9c0ca47e ("net/bnxt: save the number of EM flow count")
