tracing/probes: Fix double addition of offset for @+FOFFSET
Since commit 533059281ee5 ("tracing: probeevent: Introduce new argument
fetching code") wrongly use @offset local variable during the parsing,
the offset value is added twice when dereferencing.
Reset the @offset after setting it in FETCH_OP_FOFFS.
