kill-the-bkl/reiserfs: fix recursive reiserfs write lock in reiserfs_commit_write()

reiserfs_commit_write() is always called with the write lock held.
Thus the current calls to reiserfs_write_lock() in this function are
acquiring the lock recursively.
We can safely drop them.

This also solves further assumptions for this lock to be really
released while calling reiserfs_write_unlock().
