The libfc discovery layer is being initialized in the
'create' paths for both legacy libfcoe module parameters
and fcoe_sysfs control interfaces. The problem is that
for VN2VN mode the discovery layer is initialized as if
it were in 'fabric' mode and it is not re-configured when
the mode is changed to 'vn2vn'.
This patch splits out code that needs to be initialized
once and code that can, and should be, re-configured when
the mode changes. Additionally this patch makes that change
so that the discovery layer can be reconfigured to the
libfcoe implementation when in 'vn2vn' mode.
