fs/ntfs/aops.c: don't disable interrupts during kmap_atomic()
ntfs_end_buffer_async_read() disables interrupts around kmap_atomic(). This is a leftover from the old kmap_atomic() implementation which relied on fixed mapping slots, so the caller had to make sure that the same slot could not be reused from an interrupting context. kmap_atomic() was changed to dynamic slots long ago and commit 1ec9c5dd ("include/linux/highmem.h: remove the second argument of k[un]map_atomic()") removed the slot assignements, but the callers were not checked for now redundant interrupt disabling. Remove the conditional interrupt disable.
