devlink: Use DIV_ROUND_UP_ULL in DEVLINK_HEALTH_SIZE_TO_BUFFERS
When building this code on a 32-bit platform such as ARM, there is a
link time error (lld error shown, happpens with ld.bfd too):
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by devlink.c
>>> net/core/devlink.o:(devlink_health_buffers_create) in archive built-in.a
This happens when using a regular division symbol with a u64 dividend.
Use DIV_ROUND_UP_ULL, which wraps do_div, to avoid this situation.
Fixes: cb5ccfbe73b3 ("devlink: Add health buffer support")
