nbd: fix 64-bit division
We have this:
ERROR: "__aeabi_ldivmod" [drivers/block/nbd.ko] undefined!
ERROR: "__divdi3" [drivers/block/nbd.ko] undefined!
nbd.c:(.text+0x247c72): undefined reference to `__divdi3'
due to a recent commit, that did 64-bit division. Use the proper
divider function so that 32-bit compiles don't break.
Fixes: ef77b515243b ("nbd: use loff_t for blocksize and nbd_set_size args")
