seems unfortunate to me that the __counted_by field (n_channels)
is set some distance away from the allocation of the flex-array (channels)
whose bounds it checks. It seems it would be pretty easy for a bug in the
code being updated here to result in an overrun.
But in any case, I think this is an improvement and seems correct to me.

Although it does not seem to have any untoward side-effects,
the use of ';' to separate to assignments seems more appropriate than ','.

Hi,
This short patchset provides two minor cleanups for the gve driver.
These were found by tooling as mentioned in each patch,
and otherwise by inspection.
No change in run time behaviour is intended.
Each patch is compile tested only.
