m68k: mvme16x: Remove unused sink in mvme16x_cons_write()

When building with W=1:

    arch/m68k/mvme16x/config.c: In function ‘mvme16x_cons_write’:
    arch/m68k/mvme16x/config.c:211:25: warning: variable ‘sink’ set but not used [-Wunused-but-set-variable]
      211 |         volatile u_char sink;
	  |                         ^~~~

Fix this by removing the unused variable and assignment.
