CVE-2025-71106: fs: PM: Fix reverse check in filesystems_freeze_callback()
In the Linux kernel, the following vulnerability has been resolved:
fs: PM: Fix reverse check in filesystemsfreezecallback()
The freezeallptr check in filesystemsfreezecallback() introduced by commit a3f8f8662771 ("power: always freeze efivarfs") is reverse which quite confusingly causes all file systems to be frozen when filesystemfreezeenabled is false.
On my systems it causes the WARNONONCE() in settaskfrozen() to trigger, most likely due to an attempt to freeze a file system that is not ready for that.
Add a logical negation to the check in question to reverse it as appropriate.
