Properly free vcpupin info for unplugged CPUs

Browse Source 
Remove the pointer from def->cputune.vcpupin after unplugging
the CPU and also free the bitmap contained in the structure
by calling virDomainVcpuPinDel instead of VIR_FREE.

Introduced by commit 0df1a79.

This makes virDomainLookupVcpuPin redundant.
