md/linear: avoid possible oops and array stop
Since commit ef286f6fa673cd7fb367e1b145069d8dbfcc6081 it has been important that each personality clears ->private in the ->stop() function, or sets it to a attribute group to be removed. linear.c doesn't. This can sometimes lead to an oops, though it doesn't always. Suitable for 2.6.33-stable and 2.6.34. Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org
