fils: pragma false positive for uninitialized variable 

On musl-gcc the compiler is giving a warning for igtk_key_index
and gtk_key_index being used uninitialized. This isn't possible
since they are only used if gtk/igtk are non-NULL so pragma to
ignore the warning.

src/fils.c: In function 'fils_rx_associate':
src/fils.c:580:17: error: 'igtk_key_index' may be used uninitialized
	in this function [-Werror=maybe-uninitialized]
  580 |                 handshake_state_install_igtk(fils->hs,
					igtk_key_index,igtk + 6,
					igtk_len - 6, igtk);

(same error for gtk_key_index)
