[PATCH 2/3] sysfs: fix sysfs_dir_close memory leak

[Greg KH <greg@kroah.com>]

sysfs_dir_close did not free the "cursor" sysfs_dirent used for keeping
track of position in the list of sysfs_dirent nodes.  Consequently,
doing a "find /sys" would leak a sysfs_dirent for each of the 1140
directories in my /sys tree, or about 36kB each time.
