net: ethtool: not call vzalloc for zero sized memory request
NULL or ZERO_SIZE_PTR will be returned for zero sized memory
request, and derefencing them will lead to a segfault
so it is unnecessory to call vzalloc for zero sized memory
request and not call functions which maybe derefence the
NULL allocated memory
this also fixes a possible memory leak if phy_ethtool_get_stats
returns error, memory should be freed before exit
