Current code registers va-md entry with static name 'qdf_va_md' when loading wlan driver, with no unregister upon failure or driver unloading, this has a problem when multiple wlan drivers are present, in which case it will try to load all one by one during system bootup, but only one driver will be loaded successfully at last. The notifier_block for the unexpected wlan drivers will be left in the notifier chain, which will result in kernel panic when collecting minidump. We can improve this by registering va-md entry with module name, and unregistering the entry during de-init with the newly added API qcom_va_md_unregister(), then different wlan driver will register va-md entry with different module name, and the entry will be unregistered on loading failure or unloading, then there will be no stale notifier_block.
