Fix crash on OOM in qemuAddRBDHost

When parsing the RBD hosts, it increments the 'nhosts' counter
before increasing the 'hosts' array allocation. If an OOM then
occurs when increasing the array allocation, the cleanup block
will attempt to access beyond the end of the array. Switch
to using VIR_EXPAND_N instead of VIR_REALLOC_N to protect against
this mistake
