vtnet: Avoid ifdefs based on __NO_STRICT_ALIGNMENT

Description

vtnet: Avoid ifdefs based on __NO_STRICT_ALIGNMENT

Some platforms require an adjustment of the ethernet hearders. Rather
than make this be on __NO_STRICT_ALIGNMENT being defined, define
VTNET_ETHER_ALIGN to be either 0 or ETHER_ALIGN (aka 2). Add a test to
the if statements to only do them when != 0. This eliminates the #ifdef
sprinkled in the code, still communicates the intent and gives the same
compiled results.
