Colin Ian King ffdf16edfb drm/i915/gvt: fix memory leak of a cmd_entry struct on error exit path 
The error exit path when a duplicate is found does not kfree and cmd_entry
struct and hence there is a small memory leak.  Fix this by kfree'ing it.

Detected by CoverityScan, CID#1370198 ("Resource Leak")

Fixes: be1da7070a ("drm/i915/gvt: vGPU command scanner")
