objtool: Enclose contents of unreachable() macro in a block
Guenter Roeck reported a boot failure in mips64. It was bisected to the following commit:d1091c7fa3
("objtool: Improve detection of BUG() and other dead ends") The unreachable() macro was formerly only composed of a single statement. The above commit added a second statement, but neglected to enclose the statements in a block.
