linux-initrd: Use 'call-with-error-handling' when booting.
* guix/build/linux-initrd.scm (canonicalize-device-spec): When label resolution fails, call 'error' instead of 'format' + 'start-repl'. (boot-system): Wrap most of body in 'call-with-error-handling'. Remove 'catch' around 'primitive-load' call.master
