bnxt_en: Refactor bnxt_free_ctx_mem()

[ Upstream commit 968d2cc07c2fc9a508a53bd2de61200f50206fbc ]

Add a new function bnxt_free_one_ctx_mem() to free one context
memory type.  bnxt_free_ctx_mem() now calls the new function in
the loop to free each context memory type.  There is no change in
behavior.  Later patches will further make use of the new function.
