Masami Hiramatsu (Google) 3b76d92636 tracing/probes: Fix to update dynamic data counter if fetcharg uses it
[ Upstream commit e38e2c6a9efc435f9de344b7c91f7697e01b47d5 ]

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.
