Remove Mutexes in phy_stub_UE.c 

Various mutexes are present in the phy_stub_UE.c file. However, it will
only be run in a single thread; the multiple-thread implementation also
runs the higher layers concurrently, which leads to races and segfaults.
Therefore, remove these mutexes, as we don't need them.
