[PATCH v2 7/9] fabrics: use "const char *" in struct config

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

This is easily done, and allows passing in some const char* pointers
that would otherwise need to be strdup()d first.

Do not use const char * for cfg->device, because we may need to free()
it.
