Subject: [PATCH v2 43/52] m68k: sun3: Remove unused start_page in sun3_bootmem_alloc()

When building with W=1:

    arch/m68k/sun3/config.c: In function ‘sun3_bootmem_alloc’:
    arch/m68k/sun3/config.c:110:23: warning: variable ‘start_page’ set but not used [-Wunused-but-set-variable]
      112 |         unsigned long start_page;
	  |                       ^~~~~~~~~~

Fix this by removing the variable and the assignment, now the last user
is gone.
