[PATCH][XENIAL][SRU] rfkill: fix missing return on rfkill_init

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

BugLink: http://bugs.launchpad.net/bugs/1764810

An previous backport to bug LP: #1745130 overlooked adding in
an error return that was introduced by commit 6124c53edeea. Fix
this by adding in the missing return.

Detected by CoverityScan, CID#1467925 ("Missing return statement)
