Subject: [PATCH] misc: genwqe: Fix potential memory leak when pinning memory

Fix a memory leak in the genwqe_pin_mem() error path as called by
ioctl GENWQE_PIN_MEM. In case there is an error encountered when
mapping memory, the already allocated dma_mapping struct needs to
be freed correctly.

Detected by Coverity: CID 1162606.
