[PATCH 10/14] ipw2200: Fix kernel Oops if cmdlog debug is enabled

[Zhu Yi]

When command error log debug is enabled, we write every host command and
parameters into a buffer. But we didn't alloc the parameter buffer for this
case. The patch adds struct cmdlog_host_cmd so that the buffer is allocated
from the stack.
