ubi: Put MTD device after it is not used

Browse Source 
[ Upstream commit b95f83ab762dd6211351b9140f99f43644076ca8 ]

The MTD device reference is dropped via put_mtd_device, however its
field ->index is read and passed to ubi_msg. To fix this, the patch
moves the reference dropping after calling ubi_msg.
