ppc: Remove a potential overflow in muldiv64()
The coccinelle script: scripts/coccinelle/overflow_muldiv64.cocci gives us a list of potential overflows in muldiv64() (the two first parameters are 64bit values). This patch fixes one, as the fix seems obvious: replace muldiv64(a, b, c) by muldiv64(b, a, c) as "a" and "b" are 64bit values but a <= NANOSECONDS_PER_SECOND. (10^9 -> 30bit value).
