[PATCH 26/46] kernel: Mark functions as static in kernel/trace/trace.c

[Rashika Kheria]

Mark functions as static in kernel/trace/trace.c
because they are not used outside this file.

This eliminates the following warning in kernel/trace/trace.c:
kernel/trace/trace.c:266:9: warning: no previous prototype for âbuffer_ftrace_nowâ [-Wmissing-prototypes]
kernel/trace/trace.c:590:6: warning: no previous prototype for âfree_snapshotâ [-Wmissing-prototypes]
