[Crash-utility] [PATCH] symbol: fix offset print for function pointers that return pointers
In the show_member_offset() function, when trying to handle function
pointers, the case for "(*" is handled. However, if the function
pointer returns a pointer or a pointer to a pointer, then the
condition is unhandled. This results in the offset not being printed.
Fix by first checking if the member is potentially a function pointer,
then checking if it returns a pointer or a pointer to a pointer.
