Masami Hiramatsu (Google) b66a1defb2 tracing/probes: Fix to update dynamic data counter if fetcharg uses it ...

[ Upstream commit e38e2c6a9e ]

Fix to update dynamic data counter ('dyndata') and max length ('maxlen')
only if the fetcharg uses the dynamic data. Also get out arg->dynamic
from unlikely(). This makes dynamic data address wrong if
process_fetch_insn() returns error on !arg->dynamic case.
