remoteproc: k3-r5: Jump to error handling labels in start/stop errors

commit 188d152c0bb70f2fc12d8e3a163f2c594aa0032c from
git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git



In case of errors during core start operation from sysfs, the driver
directly returns with the -EPERM error code. Fix this to ensure that
mailbox channels are freed on error before returning by jumping to the
'put_mbox' error handling label. Similarly, jump to the 'out' error
handling label to return with required -EPERM error code during the
core stop operation from sysfs.
