[PATCH, resend] kfifo: initialize fifo accordingly to C99 standard

[Andy Shevchenko]

When build a kernel with "make W=1" we will get a warning about missing
initializer. It comes from kfifo usage style. The DEFINE_KFIFO macro doesn't
initialize the buf[] field of the fifo structure. So, using C99 style helps in
such case.
