Haotian Zhang d1ffd3c633 hwspinlock: omap: Handle devm_pm_runtime_enable() errors ...

[ Upstream commit 3bd4edd67b ]

Although unlikely, devm_pm_runtime_enable() can fail due to memory
allocations. Without proper error handling, the subsequent
pm_runtime_resume_and_get() call may operate on incorrectly
initialized runtime PM state.

Add error handling to check the return value of
devm_pm_runtime_enable() and return on failure.
