drivers: base: component: fix memory leak with using debugfs_lookup()

Browse Source 
[ Upstream commit 8deb87b1e810dd558371e88ffd44339fbef27870 ]

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once.
