m68k: sun3: Remove unused vsprintf() return value in prom_printf()

When building with W=1:

    arch/m68k/sun3/prom/printf.c: In function ‘prom_printf’:
    arch/m68k/sun3/prom/printf.c:28:13: warning: variable ‘i’ set but not used [-Wunused-but-set-variable]
       28 |         int i;
	  |             ^

As the return value of vsprintf() is unused, and serves no practical
purpose here, fix this by removing the variable.
