ice: Don't reject odd values of usecs set by user
Currently if a user sets an odd [tx|rx]-usecs value through ethtool, the request is denied because the hardware is set to have an ITR granularity of 2us. This caused poor customer experience. Fix this by aligning to a register allowed value, which results in rounding down. Also, print a once per ring container type message to be clear about our intentions. Also, change the ITR_TO_REG define to be the bitwise and of the ITR setting and the ICE_ITR_MASK. This makes the purpose of ITR_TO_REG more obvious.
