[PATCH -tip] Documentation/accounting/getdelays.c intialize the variable before using it

[Jaswinder Singh Rajput <jaswinder@kernel.org>]

May be in some cases cmd_type will be used uninitialized.

Also fixes compilation warning:

   CC [M]  Documentation/DocBook/procfs_example.o
  Documentation/accounting/getdelays.c: In function ‘main’:
  Documentation/accounting/getdelays.c:249: warning: ‘cmd_type’ may be used uninitialized in this function
