block/sed-opal: Fix trailing semicolon

The trailing semicolon is an empty statement that does no operation. Removing it since it doesn't do anything.

Hi,

Similar to the other drivers/clocksource/ patch [0].

After fixing the same thing in drivers/staging/rtl8723bs/, Joe Perches suggested I fix it treewide [1].

Best regards
Luis
