[PATCH 3.16 30/99] brcmfmac: Fix memory leak in brcmf_usbdev_qinit

[Ben Hutchings]

3.16.84-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>

commit 4282dc057d750c6a7dd92953564b15c26b54c22c upstream.

In the implementation of brcmf_usbdev_qinit() the allocated memory for
reqs is leaking if usb_alloc_urb() fails. Release reqs in the error
handling path.

Fixes: 71bb244ba2fd ("brcm80211: fmac: add USB support for bcm43235/6/8 chipsets")
