rpmb: fix error path in rpmb_dev_register()
Until this patch was rpmb_dev_register() always freeing rdev in the error
path. However, past device_register() it must not do that since the memory
is now managed by the device even if it failed to register properly. So fix
this by doing a put_device() before returning the error code.
Fixes the smatch warning:
drivers/misc/rpmb-core.c:204 rpmb_dev_register()
warn: freeing device managed memory (leak): 'rdev'
Fixes: 1e9046e3a154 ("rpmb: add Replay Protected Memory Block (RPMB) subsystem")
