[PATCH 2/5] libext2fs: Fix SET_BMAP bugs in ext2fs_bmap() and ext2fs_bmap2()

[Theodore Ts'o <tytso@mit.edu>]

Don't byte-swap the block number when setting i_block[x], since the
write_inode function will take of byte swapping the inode.

The phys_blk parameter contains an input parameter in the SET_BMAP
case, so it must be passed to ext2fs_bmap2() from the legacy function
ext2fs_bmap().
