tee: qcomtee: initialize result before use in release worker
Initialize result to 0 so the error path doesn't read it
uninitialized when the invoke fails. Fixes a Smatch warning.

Enable userspace to allocate shared memory with QTEE. Since
QTEE handles shared memory as object, a wrapper is implemented
to represent tee_shm as an object. The shared memory identifier,
obtained through TEE_IOC_SHM_ALLOC, is transferred to the driver using
TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_INPUT/OUTPUT.
