Adrian Hunter 1550217a8b mmc: mmc_test: Remove local_irq_{save,restore}() around sg_copy_{from,to}_buffer()
sg_copy_{from,to}_buffer() call sg_copy_buffer() which uses an
sg_mapping_iter with flag SG_MITER_ATOMIC, so then sg_miter_next() uses
kmap_atomic() to map pages.

A long time ago the kmap_atomic API required a slot to be provided which
risked the possibility that other code might use the same slot at the
same time. Disabling interrupts prevented the possibility of an interrupt
handler doing that. However, that went away with
commit 3e4d3af501 ("mm: stack based kmap_atomic()").

Remove local_irq_{save,restore}() around sg_copy_{from,to}_buffer().
