[PATCH 2/3] bsd-user/mmap: use TSA_NO_TSA to suppress clang TSA warnings

[Emanuele Giuseppe Esposito]

QEMU does not compile when enabling clang's thread safety analysis
(TSA),
because some functions create wrappers for pthread mutexes but do
not use any TSA macro. Therefore the compiler fails.

In order to make the compiler happy and avoid adding all the
necessary macros to all callers (lock functions should use
TSA_ACQUIRE, while unlock TSA_RELEASE, and this applies to allusers of 
pthread_mutex_lock/pthread_mutex_unlock),
simply use TSA_NO_TSA to supppress such warnings.
