lsm: use lsm_prop in security_inode_getsecid
Change the security_inode_getsecid() interface to fill in a
lsm_prop structure instead of a u32 secid. This allows for its
callers to gather data from all registered LSMs. Data is provided
for IMA and audit. Change the name to security_inode_getlsmprop().
