thread.h: Remove trailing semicolons from Coverity qemu_mutex_lock() etc

All the Coverity-specific definitions of qemu_mutex_lock() and friends
have a trailing semicolon. This works fine almost everywhere because
of QEMU's mandatory-braces coding style and because most callsites are
simple, but target/s390x/sigp.c has a use of qemu_mutex_trylock() as
an if() statement, which makes the ';' a syntax error:
"../target/s390x/sigp.c", line 461: warning #18: expected a ")"
      if (qemu_mutex_trylock(&qemu_sigp_mutex)) {
          ^

Remove the bogus semicolons from the macro definitions.
