[PATCH 5/8] platform/x86: telemetry/pltdrv: switch to devm_mutex_init()

[chitranshmandhaniya@gmail.com]

From: Chitransh Mandhaniya <Chitransh_Mandhaniya@dell.com>

Replace mutex_init() with devm_mutex_init() for both telem_lock and
telem_trace_lock so the mutex lifecycle is managed by devres.  The
driver was missing mutex_destroy() calls on the teardown path.
