Fixes these warnings (errors with --enable-checking) from GCC 6.2:

afsd.c: In function ‘afsd_run’:
afsd.c:2176:6: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]
      if (enable_rxbind)
      ^~
afsd.c:2178:3: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘if’
   afsd_syscall(AFSOP_ADVISEADDR, code, addrbuf, maskbuf, mtubuf);
   ^~~~~~~~~~~~
afsd.c:2487:5: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]

     ^~
afsd.c:2490:2: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘if’

  ^~~~~~~~~~~~
