host: use a bigger kernel buffer for mdevd
This should fix a boot error on a Thinkpad P51s: > mdevd: fatal: unable to receive netlink message: No buffer space available From the mdevd documentation[1]: > • -b kbufsz : try and reserve a kernel buffer of kbufsz bytes for > the netlink queue. Too large a buffer wastes kernel memory; too > small a buffer risks losing events. The default is 500 kB, which > should be enough for most systems; if you're getting "No buffer > space available" errors from mdevd at coldplug time, try > increasing this number. The new value of 128MiB is used by default by both udev and Busybox's mdev.
