drm/xe: Use drmm_mutex_init for VRAM manager lock

Browse Source 
Replace mutex_init()/mutex_destroy() with drmm_mutex_init() for the
VRAM manager lock. This leverages DRM managed infrastructure to
automatically destroy the mutex during device teardown, eliminating
manual mutex_destroy() calls in both the normal fini path and the
gpu_buddy_init() error path.
