host/mesh: fix loopback in net

Browse Source 
net_buf structure in Zephyr has field user_data, which was wrongly
ported as os_mbuf->om_data. To stick with porting net_buf as os_mbuf
we can base on old Zephyr's implementation, which was changed in commit
dd09cbc1c455ab1e067b53f46bee7b6d50689bbc. Before it, user_data was part
of data buffer of net_buf. We can implement this the same way, so
data_buf is last N octets of os_mbuf->om_data.

Accomodate mbuf allocation and freeing to NimBLE.
