PM: suspend: Drop a misplaced pm_restore_gfp_mask() call

The pm_restore_gfp_mask() call added by commit 12ffc3b151 ("PM:
Restrict swap use to later in the suspend sequence") to
suspend_devices_and_enter() is done too early because it takes
place before calling dpm_resume() in dpm_resume_end() and some
swap-backing devices may not be ready at that point.  Moreover,
dpm_resume_end() called subsequently in the same code path invokes
pm_restore_gfp_mask() again and calling it twice in a row is
pointless.

Drop the misplaced pm_restore_gfp_mask() call from
suspend_devices_and_enter() to address this issue.
