[PATCH] Remove trace_buf_size and trace_event from the kernel boot parameters of the kdump kernel

The kdump kernel uses resources for ftrace because trace_buf_size, which
specifies the ring buffer size for ftrace, and trace_event, which specifies
a valid trace event, are not removed, but the kdump kernel does not require
ftrace.

trace_buf_size is ignored if the specified size is 0, so specify 1.
