binfmt: a.out: Fix bogus semicolon

    fs/binfmt_aout.c: In function ‘load_aout_library’:
    fs/binfmt_aout.c:311:27: error: expected ‘)’ before ‘;’ token
      311 |    MAP_FIXED | MAP_PRIVATE;
	  |                           ^
    fs/binfmt_aout.c:309:10: error: too few arguments to function ‘vm_mmap’
      309 |  error = vm_mmap(file, start_addr, ex.a_text + ex.a_data,
	  |          ^~~~~~~
    In file included from fs/binfmt_aout.c:12:
    include/linux/mm.h:2626:35: note: declared here
     2626 | extern unsigned long __must_check vm_mmap(struct file *, unsigned long,
	  |                                   ^~~~~~~

Fix this by reverting the accidental replacement of a comma by a
semicolon.
