net/mlx5e: Add missing increment of count

commit 5ee02b7a800654ff9549807bcf0b4c9fd5cf25f9 upstream.

Add mistakenly missing increment of count variable when looping over
output buffer in mlx5e_self_test().

This resolves the issue of garbage values output when querying with self
test via ethtool.

before:
$ ethtool -t eth2
The test result is PASS
The test extra info:
Link Test        0
Speed Test       1768697188
Health Test      758528120
Loopback Test    3288687

after:
$ ethtool -t eth2
The test result is PASS
The test extra info:
Link Test        0
Speed Test       0
Health Test      0
Loopback Test    0
