4.19-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit bbc404d20d1b46d89b461918bc44587620eda200 ]
All error handling paths, except this one, go to 'out' where release_swfw_sync() is called. This call balances the acquire_swfw_sync() call done at the beginning of the function.
Branch to the error handling path in order to correctly release some resources in case of error.
