emmc_log: Fix exit condition on vacuum logs

The logic used to check for `req_size > perst_size` then exit, however,
this means that the the persistent size left over in eMMC after dumping
run/logs is greater than the current persistent log usage. It should be
checking for less than, because that would mean the free persistent size
doesn't fix the run/logs.

This can lead to a corner cases where we never exit the loop.
Refactor the check to clear up the confusion.

Tested:
|-------total-------|
|--free--|---used---|
|--run--|

if run + 1M > free, then we can't dump the log and exit.
