Fix alignment of 'last' in autofill.

Description

Fix alignment of 'last' in autofill.

'last' is the sector number of the last usable sector. Sector
numbers start with 0. As such, 'last' is always 1 less than
the count of sectors and aligning 'last' down as-is means that
the number of free sectors is pessimized by 'alignment - 1' if
the number of usable sectors was already a multiple of the
alignment. Consequently, gpart(8) failed to create a partition
when the alignment and size were such that it would extend to
the end of the disk.
