mmc: tifm_sd: Remove local_irq_{save,restore}() around tifm_sd_transfer_data()

tifm_sd_transfer_data() calls functions that ultimate use 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 3e4d3af501cc ("mm: stack based kmap_atomic()").

When the second argument to kmap_atomic was removed by commit 482fce997e14
("mmc: remove the second argument of k[un]map_atomic()"),
local_irq_{save,restore}() should have been removed also.

Remove it now.
