[PATCH] block: swim3: Mark swim3_init() static to fix no previous prototype error

[Christophe Leroy]

With pmac32_defconfig W=1:

  CC [M]  drivers/block/swim3.o
drivers/block/swim3.c:1280:5: warning: no previous prototype for 'swim3_init' [-Wmissing-prototypes]
 1280 | int swim3_init(void)
      |     ^~~~~~~~~~

swim3_init() is called locally via module_init(), it should be static.
