virresctrl: fix starting VMs with cputune.memorytune specified 

When removing check for return value of VIR_EXPAND_N this place was
incorrectly modified causing failure to start a VM with cputune
memorytune configured with useless error message:

    error: Failed to start domain 'vm1'
    error: An error occurred, but the cause is unknown
