[PATCH] SELinux: convert to kzalloc

Browse Source 
This patch converts SELinux code from kmalloc/memset to the new kazalloc
unction.  On i386, this results in a text saving of over 1K.

Before:
text    data     bss     dec     hex filename
86319    4642   15236  106197   19ed5 security/selinux/built-in.o

After:
text    data     bss     dec     hex filename
85278    4642   15236  105156   19ac4 security/selinux/built-in.o
