Subject: [net-next 2/9] ixgbevf: minor cleanups for ixgbevf_set_itr()

From: Emil Tantilov <emil.s.tantilov@...el.com>

adapter->rx_itr_setting is not a mask so check it with == instead of &
do not default to 12K interrupts in ixgbevf_set_itr()

There should be no functional effect from these changes.
