Steven Rostedt (Red Hat) 85224da0b8 kprobes/tracing: Use trace_seq_has_overflowed() for overflow checks 
Instead of checking the return value of trace_seq_printf() and friends
for overflowing of the buffer, use the trace_seq_has_overflowed() helper
function.

This cleans up the code quite a bit and also takes us a step closer to
changing the return values of trace_seq_printf() and friends to void.
