Qi Zheng d19bd48535 OPP: fix error checking in opp_migrate_dentry()
[ Upstream commit eca4c0eea53432ec4b711b2a8ad282cbad231b4f ]

Since commit ff9fb72bc077 ("debugfs: return error values,
not NULL") changed return value of debugfs_rename() in
error cases from %NULL to %ERR_PTR(-ERROR), we should
also check error values instead of NULL.

Fixes: ff9fb72bc077 ("debugfs: return error values, not NULL")
