[PATCH 6/5] mkfs: factor finobt changes into min log size when formatting

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

Since the finobt affects the size of the log reservations, we need to
be able to include its effects in the calculation of the minimum log
size.

(Not really a problem now, but adding rmapbt will give this one some
bite.)
