Clang warns about exceeded stack frame size

  fs/smb/client/connect.c:1109:1: warning: stack frame size (1048)
  exceeds limit (1024) in 'cifs_demultiplex_thread'
  [-Wframe-larger-than]

It turns out that clean_demultiplex_info() got inlined into
cifs_demultiplex_thread(), so mark it as noinline_for_stack to save
some stack space.
