kernel: btrfs: check for read permission on src file in the clone ioctl

The existing [btrfs] code would have allowed you to clone a file that was only open for writing. Not an expected behaviour.
Upstream commit: http://git.kernel.org/linus/5dc6416414fb3ec6e2825fd4d20c8bf1d7fe0395 Reference: https://bugzilla.redhat.com/show_bug.cgi?id=593226I'm not requesting a CVE name for this as it did not affect any of Red Hats' supported Linux kernels.
Thanks, Eugene -- main(i) { putchar(182623909 >> (i-1) * 5&31|!!(i<7)<<6) && main(++i); }
