Add a new spdk_vbdev_module_examine_done() API which
vbdev modules can use to notify the generic bdev layer
once a base bdev examination is complete.
This is especially required for asynchronous vbdevs
like GPT which must issue I/O to the base bdev.
As part of this patch, add examine callbacks
for both split and error, which for now only call
this new functions. Later patches will move code from
the init callback to the examine callback for these
modules. examine callbacks are now required for all
vbdev modules.
