iavf: Fix missing state logs

Fix debug prints, by adding missing state prints.

Extend iavf_state_str by strings for __IAVF_INIT_EXTENDED_CAPS and
__IAVF_INIT_CONFIG_ADAPTER.

Without this patch, when enabling debug prints for iavf.h, user will
see:
iavf 0000:06:0e.0: state transition from:__IAVF_INIT_GET_RESOURCES to:__IAVF_UNKNOWN_STATE
iavf 0000:06:0e.0: state transition from:__IAVF_UNKNOWN_STATE to:__IAVF_UNKNOWN_STATE
