[PATCH] reiserfs: fix journaling issue regarding fsync() 

When write() extends a file(i_size is increased) and fsync() is called,
change of inode must be written to journaling area through fsync().
But,currently the i_trans_id is not correctly updated when i_size is
increased.  So fsync() does not kick the journal writer.

Reiserfs_file_write() already updates the transaction when blocks are
allocated, but the case when i_size increases and new blocks are not added
is not correctly treated.

Following patch fix this bug.
