[dpdk-dev] [PATCH] ixgbe: change logging for ixgbe tx code path selection

Simple and vector are different tx code paths. If vector
is selected, change logging from:
PMD: ixgbe_set_tx_function(): Using simple tx code path
PMD: ixgbe_set_tx_function(): Vector tx enabled.

to:
PMD: ixgbe_set_tx_function(): Using vector tx code path

or, if simple selected:
PMD: ixgbe_set_tx_function(): Using simple tx code path

The dangling else in the #ifdef makes readability difficult,
so resolving in way that seems most readable.
