Normally in dentry_open the passed in path is placed on the new filp
removing the caller from needing to worry about it. In the rare case
that we can not allocate a filp the path is not consumed. None of the
callers of dentry_open call path_put in their error handling when
dentry_open fails so call path_put for them on error and keep everyone's
error handling simple.
