This reverts commit 1a5874d4.

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.

also added a log message for DCI generation in MAC

changed uint8_t to void as return is not used in the calling function

this shouldn't affect the testing with cots ue

Created two dci_pdu's to hold dci configuration for UL and DL DCI.
This wasn't a problem before as only one DCI was scheduled.
