Rafael J. Wysocki 6db18971f7 PM: sleep: Fix error handling in dpm_prepare() ...

[ Upstream commit 544e737dea5ad1a457f25dbddf68761ff25e028b ]

Commit 2aa36604e824 ("PM: sleep: Avoid calling put_device() under
dpm_list_mtx") forgot to update the while () loop termination
condition to also break the loop if error is nonzero, which
causes the loop to become infinite if device_prepare() returns
an error for one device.

Add the missing !error check.
