[PATCH] kernel/module.c: for looping, need use 'goto' instead of 'break' to jump out in time

[Chen Gang <gang.chen@asianux.com>]

In the 'for' looping, when error occurs, the 'break' only jump out of
'switch', and still in 'for' looping.  If error occurs multiple times,
the original error value will be overwrite.

Currently, that will not cause issue, but still better to improve it,
so that let it return the first real error code in time.
