 Modified Files:
        src/sys/ufs/ext2fs: ext2fs_inode.c
        src/sys/ufs/ffs: ffs_inode.c

 Log Message:
 - ufs_balloc_range(): on error, only PG_RELEASED the pages that were
   allocated to extend the file to the new size. Releasing all pages
   may release pages that contains previously-written data not yet flushed
   to disk. Should fix PR kern/35704
 - {ffs,lfs,ext2fs}_truncate(): Even if the inode's size is the same as
   the new length, call uvm_vnp_setsize(). *_truncate() may have been
   called by *_write() in the error path (e.g. block allocation failure
   because of quota of file system full), and at this point v_writesize
   has been set to the desired size of the file and not reverted to the
   old size. Not adjusting v_writesize to the real size cause
   genfs_do_io() to write to disk past the real end of the file.
