WifiLogger: revert large ringbuffers for userdebug/eng

When the WiFi code is sufficiently mature, we'll use
this patch to return to using small ring buffers
on all builds.

Note that this patch is not a literal/full revert of
CL:1048267. The reason for the more focused change
is to minimize merge conflicts, in case other code
changes by the time this CL lands.
