iavf: Fix race condition between iavf_shutdown and iavf_remove

Browse source

Fix a deadlock introduced by commit
974578017f ("iavf: Add waiting so the port is initialized in remove")
due to race condition between iavf_shutdown and iavf_remove, where
iavf_remove stucks forever in while loop since iavf_shutdown already
set __IAVF_REMOVE adapter state.

Fix this by checking if the __IAVF_IN_REMOVE_TASK has already been
set and return if so.
