usb: dwc3: qcom: Fix potential memory leak

Browse source

[ Upstream commit 097fb3ee71 ]

Function dwc3_qcom_probe() allocates memory for resource structure
which is pointed by parent_res pointer. This memory is not
freed. This leads to memory leak. Use stack memory to prevent
memory leak.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
