linux-modules: Correctly propagate error code from 'init_module'.

Browse Source 
* gnu/packages/patches/guile-linux-syscalls.patch (scm_load_linux_module):
  Leave 'errno' unchanged when ERR != 0.
* gnu/build/linux-modules.scm (load-linux-module*): Check for the errno
  value of ARGS to determine whether the module was already loaded.
