[ Upstream commit 29cd13cfd7624726d9e6becbae9aa419ef35af7f ]
In the impelementation of v3d_submit_cl_ioctl() there are two memory
leaks. One is when allocation for bin fails, and the other is when bin
initialization fails. If kcalloc fails to allocate memory for bin then
render->base should be put. Also, if v3d_job_init() fails to initialize
bin->base then allocated memory for bin should be released.
Fixes: a783a09ee76d ("drm/v3d: Refactor job management.")
