soc: qcom: smem: fix hwspinlock resource leak in probe error paths

Browse source

[ Upstream commit dc5db35073 ]

The hwspinlock acquired via hwspin_lock_request_specific() is not
released on several error paths. This results in resource leakage
when probe fails.

Switch to devm_hwspin_lock_request_specific() to automatically
handle cleanup on probe failure. Remove the manual hwspin_lock_free()
in qcom_smem_remove() as devm handles it automatically.
