make an A or B type decision instead of a security decision.  Currently
this is the case at least for filesystems when deciding if a process can use
the reserved 'root' blocks and for the case of things like the oom
algorithm determining if processes are root processes and should be less
likely to be killed.  These types of security system requests should not be
audited or logged since they are not really security decisions.  It would be
possible to solve this problem like the vm_enough_memory security check did
by creating a new LSM interface and moving all of the policy into that
interface but proves the needlessly bloat the LSM and provide complex
indirection.

This merely allows those decisions to be made where they belong and to not
flood logs or printk with denials for thing that are not security decisions.

If an invalid (large) capability is requested the capabilities system
may panic as it is dereferencing an array of fixed (short) length.  Its
possible (and actually often happens) that the capability system
accidentally stumbled into a valid memory region but it also regularly
happens that it hits invalid memory and BUGs.  If such an operation does
get past cap_capable then the selinux system is sure to have problems as
it already does a (simple) validity check and BUG.  This is known to
happen by the broken and buggy firegl driver.

This patch cleanly checks all capable calls and BUG if a call is for an
invalid capability.  This will likely break the firegl driver for some
situations, but it is the right thing to do.  Garbage into a security
system gets you killed/bugged
