Mario Limonciello (AMD) 862b0e6393 PM: hibernate: Use atomic64_t for compressed_size variable 
commit 66ededc694 upstream.

`compressed_size` can overflow, showing nonsensical values.

Change from `atomic_t` to `atomic64_t` to prevent overflow.

Fixes: a06c6f5d3c ("PM: hibernate: Move to crypto APIs for LZO compression")
