atl1: remove unnecessary crc inversion

The original vendor driver contained a private ether_crc_le() function
that produced an inverted crc.  When we changed to the kernel version of
ether_crc_le(), we neglected to undo the inversion.  Let's do it now.
Discovered by and patch proffered by Jose Alberto Reguero.
