[PATCH] mwifiex: pcie: Fix memory leak in mwifiex_pcie_alloc_cmdrsp_buf

[Navid Emamdoost]

In mwifiex_pcie_alloc_cmdrsp_buf, a new skb is allocated which should be
released if mwifiex_map_pci_memory() fails. The release is added.

Fixes: fc3314609047 ("mwifiex: use pci_alloc/free_consistent APIs for PCIe")
