mmc: tmio_mmc_core: Remove local_irq_{save,restore}() around k[un]map_atomic()

Browse source

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()").

When the second argument to kmap_atomic was removed by commit 482fce997e
("mmc: remove the second argument of k[un]map_atomic()"),
local_irq_{save,restore}() should have been removed also.

Remove it now.
