ftrace: Only update $offset when we update $ref_func
The value of $offset should be the offset of $ref_func from the
beginning of the object file. Therefore, we should set both variables
together.
This fixes a bug I was hitting on sh where $offset (which is used to
calcualte the addends for the __mcount_loc entries) was being set
multiple times and didn't correspond to $ref_func's offset in the object
file. The addends in __mcount_loc were calculated incorrectly, resulting
in ftrace dynamically modifying addresses that weren't mcount call
sites.
