[PATCH 1/1 linux-next] hp100: simplify hp100_module_init

-Avoid double goto and directly return err where possible.
-Remove unused labels which fixes:

drivers/net/ethernet/hp/hp100.c:3047:2: warning: label
'out3' defined but not used [-Wunused-label]

This is untested.

Having a sole lone return statement that all flows of control
branch to makes the code easier to audit, than to have a huge
block where each return statement has to be audited independently
for potential cleanups.

Added to the fact that this patch is completely untested, I'm
not applying this, sorry.
