Breno Leitao 137ee2f5d1 jsm: fixing error if the driver fails to load 
Currently if the driver fails to register on port, the kernel
crashes with the following stack:

cpu 0x1: Vector: 300 (Data Access) at [c0000000e0303090]
    pc: c00000000039aa74: .__mutex_lock_slowpath+0x44/0x10c

This patch just fixes the code flow to abort the load when an
error is detected.
