ixgbe: ptp code cleanup
This patch fixes two minor nits from Richard Cochran. The first is a case of ambitious line wrapping that wasn't necessary. The second is to re-order the flag checks for PPS support. Previously, the hardware test was done first, and the interrupt flag test was done second. Now, test the interrupt flag and use the unlikely macro.
