Remove superfluous STAT_FORMATTED

STAT_FORMATTED is only used inside snap_to_mebibyte() to suppress
enforcement that partition boundaries must not overlay the MBR or EBRs
when merely formatting existing partitions.  However since commit [1],
snap_to_mebibyte() is only called inside the dialogs composing Create
New, Copy / Paste into New and Resize / Move operations and never when
composing a Format operation or any other operation which doesn't change
partition boundaries.  Therefore remove STAT_FORMATTED.
