migration: Update qemu_file_get_return_path() docs and remove dead checks
The documentation of qemu_file_get_return_path() states that it can
return NULL on failure. However, a review of the current implementation
reveals that it is guaranteed that it will always succeed and will never
return NULL.

As a result, the NULL checks post calling the function become redundant.
This commit updates the documentation for the function and removes all
NULL checks throughout the migration code.
