Steven Hartland 86787e8d97 Fix early kernel dump via dumpdev env
Setting the dumpdev via env e.g. loader.conf provides the ability to
configure the kernel dump device during early boot. When using this
g_io_getattr was returning EPERM due to cp->acr == 0.

Fix this by calling g_access to ensure we're a read consumer prior
to calling g_dev_setdumpdev.
