Functions virDomainSoundCodecDefFree(), virCapabilitiesFreeStoragePool() and virStorageSourceNVMeDefFree() are doing 'if (ptr)' NULL checks right before a 'VIR_FREE(ptr)' call.
VIR_FREE() is a wrapper for g_free(). g_free(mem) documentation [1] states: 'If mem is NULL it simply returns, so there is no need to check mem against NULL before calling this function.' This patch removes these needless NULL checks. The virDomainSoundCodecDefFree() instance was found by accident via code inspection, the other 2 instances were found using Coccinelle.
