net: cpsw: Loop until interface ready or timeout in cpsw_slave_update_link()

Without this patch the first packet sent will always be dropped.

Also check for interface status in cpsw_send() only if interface is
not ready because the MII access inside cpsw_update_link() is a very
time consuming operation and significantly deteriorates performance.
