ix(4): Report RX errors as sum of all RX error counters

Browse Source 
HW keeps track of RX errors using several counters, each for
specific type of errors. Report RX errors to OS as sum
of all those counters: CRC errors, illegal bytes, checksum,
length, undersize, fragment, oversize and jabber errors.

Also, add new "rx_errs" sysctl in the dev.ix.N.mac_stats tree. This is
to provide an another way to display the sum of RX errors.
