arm/ftrace: fix ftrace_return_addr() to ftrace_return_address()
The clean up of CALLER_ADDR*() functions required the archs to either use the default __builtin_return_address(X) (where X > 0) or override it with something the arch can use. To override it, the arch would define ftrace_return_address(x). The arm architecture requires this to be redefined but instead of defining ftrace_return_address(x) it defined ftrace_return_addr(x).
