[PATCH] alx: revise self-test flag for external loopback

[xiong]

in previous code, etest->flag is
(ETH_TEST_FL_OFFLINE | ETH_TEST_FL_EXTERNAL_LB),
for command 'ethtool -t ethX external_lb'.
and the bug-code cause external loopback wouldn't be excuted.
revising the flag test condition from '==' to "&' to fix this bug.

PS.
ethtool is a Linux command for displaying or modifying the NIC parameters.
such as disable/enable TSO or checksum offload, dump chip specific registers,
statistics, link detection, diagnostic (self tst), and so on....
see https://www.kernel.org/pub/software/network/ethtool
for detail.
