bnxt_en: Fix RSS table size check when changing ethtool channels

Browse source

[ Upstream commit 0d9a60a061 ]

When changing channels, the current check in bnxt_set_channels()
is not checking for non-default RSS contexts when the RSS table size
changes. The current check for IFF_RXFH_CONFIGURED is only sufficient
for the default RSS context. Expand the check to include the presence
of any non-default RSS contexts.

Allowing such change will result in incorrect configuration of the
context's RSS table when the table size changes.
