scatterlist: do not disable IRQs in sg_copy_buffer
Commit 50bed2e2862a ("sg: disable interrupts inside sg_copy_buffer")
introduced disabling interrupts in sg_copy_buffer() since atomic uses of
miter required it due to use of kmap_atomic().
However, as commit 8290e2d2dcbf ("scatterlist: atomic sg_mapping_iter() no
longer needs disabled IRQs") acknowledges disabling interrupts is no
longer needed for calls to kmap_atomic() and therefore unneeded for miter
ops either, so remove it from sg_copy_buffer().
