mtd: call external _get and _put in right order
MTD provider provides mtd_info object to mtd subsystem.
With kref patch the mtd_info object can be alive after
provider released mtd device.
Fix calling order in _get and _put functions to allow
mtd provider to safely alloc and release mtd object.
Execute:
1) call external _get
2) get_module
3) add internal kref
in the get function and opposite order in the put one.
The _put_device callback should be the last in put
as the master struct memory may be freed in this callback.
