tracing: Fix function name for trampoline
The issue that unrelated function name is shown on stack trace like following even though it should be trampoline code address is caused by the creation of trampoline code in the area where .init.text section of module was freed after module is loaded. bash-1344 [002] ..... 43.644608: <stack trace> => (MODULE INIT FUNCTION) => vfs_write => ksys_write => do_syscall_64 => entry_SYSCALL_64_after_hwframe To resolve this, when function address of stack trace entry is in trampoline, output without looking up symbol name.
