c_SRS was 61, which does not fit for 106 PRBs as it seems. Value 0 works.
Maybe not the right thing to do though (see 38.211 6.4.1.4.3,
table 6.4.1.4.3-1).

Also it seems necessary to pass desired LTE/NR bands when requesting
LTE UE capabilities. Today this is hardcoded, to be done better at
some point. We should get the bands from the eNB configuration and
the eNB/gNB X2 exchanges.

Also fixed bugs in ulsim and dlsim harq tests
