[ Upstream commit d3cfe7ddbc3dfbb9b201615b7fef8fd66d1b5fe8 ]
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: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
