Darrick J. Wong ab2cd4a4d2 e2fsck: don't flush the FS unless it's actually dirty 
ext2fs_flush2() unconditionally writes the block group descriptors to
disk even if the underlying FS isn't marked dirty.  This causes the
following error message on a fsck -n run:

e2fsck 1.43-WIP (09-Jul-2014)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
Error writing block 2 (Attempt to write block to filesystem resulted in short write).  Ignore error? no

Error writing block 2 (Attempt to write block to filesystem resulted in short write).  Ignore error? no

Error writing file system info: Attempt to write block to filesystem resulted in short write

Since ext2fs_close2() only calls flush if the dirty flag is set,
modify e2fsck to exhibit the same behavior so that we don't spit out
write errors for a read only check.
