scsi: core: Reduce memory required for SCSI logging
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.
