drm/panfrost: Fix a double-free error
drm_gem_shmem_create_with_handle() returns a GEM object and attach a
handle to it. When the user closes the DRM FD, the core releases all
GEM handles along with their backing GEM objs, which can lead to a
double-free issue if panfrost_ioctl_create_bo() failed and went
through the err_free path where drm_gem_object_put_unlocked() is
called without deleting the associate handle.
Replace this drm_gem_object_put_unlocked() call by a
drm_gem_handle_delete() one to fix that.
