We will need to dynamically allocate and change indirection tables
for additional RSS contexts.  Add the rss_ctx pointer parameter to
bnxt_alloc_rss_indir_tbl() and bnxt_set_dflt_rss_indir_tbl().
Existing usage will always pass rss_ctx as NULL which means the
default RSS context.

When supporting additional RSS contexts in subsequent patches, we'll
pass the valid rss_ctx to these 2 functions.
