uio: mark uio.h functions __KERNEL__ only

Browse source 
To avoid userspace build failures such as:

.../linux/uio.h:37: error: expected `=', `,', `;', `asm' or `__attribute__' before `iov_length'
.../linux/uio.h:47: error: expected declaration specifiers or `...' before `size_t'

move uio functions inside a __KERNEL__ block.
