gpu: nvgpu: allow bind to be interrupted
This change solves two problems:
(*) the possibility of a crash due to interrupting the gpu
initialization following a bind
(*) a IOVA memory leak that could prevent the GPU from binding after
about 200 bind/unbind cycles
A detailed list of fixes:
- chek that arbiter is initialized before freeing it.
- do not re-enable interrupts when MSI is enabled on unbind.
- free the semaphore sea on unbind.
- ensure we dont double load the vbios.
- check return value of nvgpu_mutex_init for semaphores.
- add corresponding nvgpu_mutex_destroy calls.
