igb: Fix a test with HWTSTAMP_TX_ON
'HWTSTAMP_TX_ON' should be handled as a value, not as a bit mask.
The modified code should behave the same, because HWTSTAMP_TX_ON is 1
and no other possible values of 'tx_type' would match the test.
However, this is more future-proof, should other values be allowed one day.
See 'struct hwtstamp_config' in 'include/uapi/linux/net_tstamp.h'
This fixes a warning reported by smatch:
igb_xmit_frame_ring() warn: bit shifter 'HWTSTAMP_TX_ON' used for logical '&'
