When a function like devm_clk_get_optional() function returns both error
pointers on error and NULL then the NULL return means that the optional
feature is deliberately disabled. It is a special sort of success and
should not trigger an error message. The surrounding code should be
written to check for NULL and not crash.
On the other hand, if we encounter an error, then the probe from should
clean up and return a failure.
In this code, if devm_clk_get_optional() returns an error pointer then
the kernel will crash inside the call to:
clk_set_rate(qcadev->susclk, SUSCLK_RATE_32KHZ);
The error handling must be updated to prevent that.

This reverts commit de058420767df21e2b6b0f3bb36d1616fb962032.
There is no actual tipc_node refcnt leak as stated in the above commit.
The refcnt is hold carefully for the case of an asynchronous decryption
(i.e. -EINPROGRESS/-EBUSY and skb = NULL is returned), so that the node
object cannot be freed in the meantime. The counter will be re-balanced
when the operation's callback arrives with the decrypted buffer if any.
In other cases, e.g. a synchronous crypto the counter will be decreased
immediately when it is done.
Now with that commit, a kernel panic will occur when there is no node
found (i.e. n = NULL) in the 'tipc_rcv()' or a premature release of the
node object.
This commit solves the issues by reverting the said commit, but keeping
one valid case that the 'skb_linearize()' is failed.
