Add a new version of fpunch for operating on a snapshot ID, not a subvolume - and use it for "extent past end of inode" repair. Previously, repair would try to delete everything at once, but deleting too many extents at once can overflow the btree_trans bump allocator, as well as causing other problems - the new helper properly uses bch2_extent_trim_atomic().
