[PATCH] dm: fix mapped device ref counting
To avoid races, _minor_lock must be held while changing mapped device
reference counts.
There are a few paths where a mapped_device pointer is returned before a
reference is taken. This patch fixes them.
[akpm: too late for 2.6.17 - suitable for 2.6.17.x after it has settled]
