tracing: Fix event format export
For some reason the export of the event print format to userspace
uses '#fmt' which breaks if the format string is anything but a plain
string, for example if it is built with macros then the macro names
are exported instead of their contents.
Use
"\"%s\"", fmt
instead of
"%s", #fmt
to export the string and not the way it is built.
For example, in net/mac80211/driver-trace.h for the trace event drv_start
there is:
TP_printk(
LOCAL_PR_FMT, LOCAL_PR_ARG
)
Which use to produce:
print fmt: LOCAL_PR_FMT, REC->wiphy_name
Now produces:
print fmt: "%s", REC->wiphy_name
