Gustavo A. R. Silva 88476b2665 usb: gadget: f_phonet: Use struct_size() helper in kzalloc() ...

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.

Also, address the following sparse warnings:
drivers/usb/gadget/function/f_phonet.c:673:16: warning: using sizeof on a flexible structure
