gpu: nvgpu: skip destroy if vidmem not initialized
The vidmem shall be destroyed only if it has been
initialized. If not skipped, it accesses mutexes
which are in invalid state. This results in BUG like:
BUG: spinlock bad magic on CPU#0, rmmod/1560
Also, destroy vidmem bootstrap allocator which is
set up in nvgpu_vidmem_init().
Bug 1987855
