smsc75xx: fix smsc75xx_set_features()
[ Upstream commit 88e80c62671ceecdbb77c902731ec95a4bfa62f9 ]
If an attempt is made to disable RX checksums, USB adapter is changed
but netdev->features is not, because smsc75xx_set_features() returns a
non zero value.
This throws errors from netdev_rx_csum_fault() :
<devname>: hw csum failure
