This reverts commit f92a3b0d00, which
was commit 083a6a5078 upstream. In 4.19
there is still an option to use 32-bit sector_t on 32-bit
architectures, so we need to keep checking for truncation.
Since loop_set_status() was refactored by subsequent patches, this
reintroduces its truncation check in loop_set_status_from_info()
instead.
I tested that the loop ioctl operations have the expected behaviour on
x86_64, x86_32 with CONFIG_LBDAF=y, and (the special case) x86_32 with
CONFIG_LBDAF=n.
