staging: skein: fixed sparse warnings related to static declarations

drivers/staging/skein/skein_generic.c:30:5: warning: symbol 'skein256_update' was not declared. Should it be static?
drivers/staging/skein/skein_generic.c:65:5: warning: symbol 'skein512_update' was not declared. Should it be static?
drivers/staging/skein/skein_generic.c:100:5: warning: symbol 'skein1024_update' was not declared. Should it be static?
