hwspinlock: omap: Discard pm_runtime_put() return value

Failing driver probe due to pm_runtime_put() returning a negative value
is not particularly useful.

Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example. It also happens when the kernel
has been configured with CONFIG_PM unset.

Accordingly, update omap_hwspinlock_probe() to simply discard the
return value of pm_runtime_put().

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.
