linux-modules: Ignore EINVAL in ‘modprobe’ mode. 

Loading the framebuffer-coreboot module simply fails with EINVAL on a
non-Corebooted system.  Crashing the system with a kernel panic is not
a reasonable reaction to loading valid modules on unsupported hardware.
The kernel should log an error, which the user is expected to see.

Bogus module names will still be fatally reported by linux-modules.drv.

* gnu/build/linux-modules.scm (load-linux-module*):
Ignore EINVAL errors when operating recursively.
