[PATCH 2/3] kfifo: Fix the description of kfifo_init()

[Christophe JAILLET]

Remove a useless comment related to kfifo_init().

The size of the buffer is expected to be a power of 2, as already stated a
few liens above.

There is no point is speaking of "the number of elements" here. If
kfifo_init() is used, then the internal buffer is explicitly allocated
using a memory allocation function such a kvalloc() and the needed context
is stored in a struct kfifo. In such a case, the "size" of an element is
defined a sizeof(unsigned char) which is 1.
