Fix the regression brought by commit 5904de0d735b ("PM: hibernate: Do not get block device exclusively in test_resume mode"), which incorrectly open the swapfile in a wrong mode, and causes unexpected behavior during non-hibernation operation.
Fix it by really disabling exclusive mode under test_resume.
This is the v2 of the fix for a hibernation test_resume swapfile open issue. Chenzhou found that v1 has a warning during the stress test. It was due to broken open mode in swsusp_write(), fixes it in v2.
patch 1 is a renaming of the function parameter, to better reflects the swap device open mode. patch 2 is to fix the open mode on the swap device.
v1: https://lore.kernel.org/lkml/20230823161329.7348-1-yu.c.chen@intel.com/
