macintosh/ans-lcd: fix build failure after module_init/exit relocation

After commit 0fd972a7 ("module: relocate module_init from init.h to module.h")
ans-lcd module fails to build with:

drivers/macintosh/ans-lcd.c:201:1: warning: data definition has no type or storage class [enabled by default]
 module_init(anslcd_init);
 ^
drivers/macintosh/ans-lcd.c:201:1: error: type defaults to 'int' in declaration of 'module_init' [-Werror=implicit-int]
drivers/macintosh/ans-lcd.c:201:1: warning: parameter names (without types) in function declaration [enabled by default]
drivers/macintosh/ans-lcd.c:202:1: warning: data definition has no type or storage class [enabled by default]
 module_exit(anslcd_exit);

 anslcd_exit(void)

This commit fixes it by replacing linux/init.h by linux/module.h.
