wifi: brcmfmac: avoid invalid list operation when vendor attach fails 

[ Upstream commit b822015a1f ]

When the brcmf_fwvid_attach() fails the driver instance is not added
to the vendor list. Hence we should not try to delete it from that
list when the brcmf_fwvid_detach() function is called in cleanup path.
