LoadProhibited exception when using EspMutex #8

The implementation for EspMutex was recently changed from using a pthread_mutex_t to a *mut pthread_mutex_t. This is incorrect as when locking, the pthread_mutex_lock function calls pthread_mutex_init_if_static which dereferences the mutex pointer. Because this pointer is initially set to PTHREAD_MUTEX_INITIALIZER (0xFFFFFFFF), this causes a load to this address which is invalid and causes a LoadProhibited exception.
