drm/msm: Fix NULL pointer dereference in crashstate_get_vm_logs()
crashstate_get_vm_logs() did not check the return value of
kmalloc_array(). In low-memory situations, kmalloc_array() may return
NULL, leading to a NULL pointer dereference when the function later
accesses state->vm_logs.
Fix this by checking the return value of kmalloc_array() and setting
state->nr_vm_logs to 0 if allocation fails.
