Fix up "random: Add hook to override device reads and getrandom(2)"
RHEL-only commit 7c0b728ae37e7 ("random: Add hook to override device
reads and getrandom(2)") adds a call to import_single_range(), but that
function has been replaced by import_ubuf() and removed upstream:
6ac805d138709 ("iov_iter: remove unused 'iov' argument from import_single_range()")
9fd7874c0e5c8 ("iov_iter: replace import_single_range() with import_ubuf()")
Fix up commit 7c0b728ae37e7 to use import_ubuf() instead.
Fixes: 7c0b728ae37e7 ("random: Add hook to override device reads and getrandom(2)")
