This cleans up other usages of of vmalloc in ebtables.c. The 
changes are similar to the cleanup done in 
ebtables-fix-allocation-in-net-bridge-netfilter-ebtablesc.patch


Patch Description:

This patch makes all the vmalloc calls in net/bridge/netfilter/ebtables.c
follow the standard convention. Remove unnecessary casts, and use '*object'
instead of 'type'.
