random: replace import_single_range() with import_ubuf()
Upstream commit 6ac805d138709 dropped the iov arg from
import_single_range() and upstream commit 9fd7874c0e5c8 replaced
import_single_range() with import_ubuff(). As our patch 7c0b728ae37e7
still called import_single_range() in drivers/char/random, this needs to
be brought up to date to continue working.
