losetup: don't require 512-byte aligned offsets
Kernel aligns the device size, but the offset where the device starts
is not required to be aligned.
# losetup --offset 32 -f file.img
is just fine, the final size of the look device will be (in sectors)
(backing_file_size - offset) >> 9
so we have to do the same in userspace when we check for successful
set capacity ioctl.
