net: ena: fix incorrect test of supported hash function

Browse Source 
[ Upstream commit d3cfe7ddbc ]

ena_com_set_hash_function() tests if a hash function is supported
by the device before setting it.
The test returns the opposite result than needed.
Reverse the condition to return the correct value.
Also use the BIT macro instead of inline shift.

Fixes: 1738cd3ed3 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
