scsi: core: Reduce memory required for SCSI logging
[ Upstream commit dccc96abfb21dc19d69e707c38c8ba439bba7160 ]
The data structure used for log messages is so large that it can cause a
boot failure. Since allocations from that data structure can fail anyway,
use kmalloc() / kfree() instead of that data structure.
See also https://bugzilla.kernel.org/show_bug.cgi?id=204119.
See also commit ded85c193a39 ("scsi: Implement per-cpu logging buffer") # v4.0.
