tracing/events: Convert format output to seq_file
Two new events were added that broke the current format output.
Both from the SCSI system: scsi_dispatch_cmd_done and scsi_dispatch_cmd_timeout
The reason is that their print_fmt exceeded a page size. Since the output
of the format used simple_read_from_buffer and trace_seq, it was limited
to a page size in output.
This patch converts the printing of the format of an event into seq_file,
which allows greater than a page size to be shown.
I diffed all event formats comparing the output with and without this
patch. All matched except for the above two, which showed just:
FORMAT TOO BIG
without this patch, but now properly displays the output with this patch.
v2: Remove updating *pos in seq start function.
