eventfs: Move taking of inode_lock into dcache_dir_open_wrapper()

The both create_file_dentry() and create_dir_dentry() takes a boolean
parameter "lookup", as on lookup the inode_lock should already be taken,
but for dcache_dir_open_wrapper() it is not taken.

There's no reason that the dcache_dir_open_wrapper() can't take the
inode_lock before calling these functions. In fact, it's better if it
does, as the lock can be held throughout both directory and file
creations.

This also simplifies the code, and possibly prevents unexpected race
conditions when the lock is released.
