netfilter: Enable TOS matching in the kernel

This patch enabled kernel config CONFIG_NETFILTER_XT_MATCH_DSCP.
This adds a netfilter kernel configuration for matching TOS
packets for IPV4 packets. This will be required in certain QOS

msm: audio: qdsp6v2: Change acdb_mmap size variable to unsigned

The acdb_mmap fuction does a size calculation but
stores the result in an int which makes negitive
numbers possible. Changing the variable to unsigned
ensures that the size used is never out of bounds.
