Function frame_allocator::allocate_frames_by_bytes_deferred

pub fn allocate_frames_by_bytes_deferred(
    requested_paddr: Option<PhysicalAddress>,
    num_bytes: usize
) -> Result<(AllocatedFrames<Page4K>, DeferredAllocAction<'static>), &'static str>

Similar to allocated_frames_deferred(), but accepts a size value for the allocated frames in number of bytes instead of number of frames.

This function still allocates whole frames by rounding up the number of bytes.
