ibmveth: Use dcbf rather than dcbfl 

stable inclusion

category: bugfix

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0a809e01578bfb12aa7ac72cf83e9e818b9702a1



--------------------------------

commit bfedba3b upstream.

When building for power4, newer binutils don't recognise the "dcbfl"
extended mnemonic.

dcbfl RA, RB is equivalent to dcbf RA, RB, 1.

Switch to "dcbf" to avoid the build error.
