[ Upstream commit 702279d2ce4650000bb6302013630304e359dc13 ]

There was a typo in the code that checks for 64K BNXT_PAGE_SHIFT in
bnxt_hwrm_set_pg_attr().  Fix it and make the code more understandable
with a new macro BNXT_SET_CTX_PAGE_ATTR().

Fixes: 1b9394e5a2ad ("bnxt_en: Configure context memory on new devices.")
