Subject: [PATCH 2/5]security:ebitmap.c Fix warning: variable 'e_sft' set but not used

gcc is giving me this during compiling:
  CC      security/selinux/ss/ebitmap.o
security/selinux/ss/ebitmap.c: In function 'ebitmap_netlbl_import':
security/selinux/ss/ebitmap.c:159:27: warning: variable 'e_sft' set but not used

The below fixes this warning for me.
(please check this whenever you have time).
