drm/msm: fix missing NULL check after kcalloc in crashstate_get_bos()
The crashstate_get_bos() function allocates memory for `state->bos`
using kcalloc(), but the vmbind path does not check for allocation
failure before dereferencing it in the following drm_gpuvm_for_each_va()
loop. This could lead to a NULL pointer dereference if memory allocation
fails.
Fix this by wrapping the drm_gpuvm_for_each_va() loop with a NULL check
on state->bos, similar to the safety check in the non-vmbind path.
