Redundant NULL check in profile_trampoline function (sysmodule.c)

[chgnrdv]

Code in profile_trampoline function checks if arg argument value is equal to NULL and in this case assigns Py_None to it

cpython/Python/sysmodule.c

Lines 954 to 956 in 88a7f66

	if (arg == NULL) {
	arg = Py_None;
	}

The only place where arg is used in profile_trampoline is this call

cpython/Python/sysmodule.c

Line 959 in 88a7f66

PyObject *result = call_trampoline(tstate, self, frame, what, arg);

But similar check is already done by call_trampoline function

cpython/Python/sysmodule.c

Line 930 in 88a7f66

stack[2] = (arg != NULL) ? arg : Py_None;

My suggestion is to remove excess check from profile_trampoline.
