bsc: fix TC_paging_imsi_a_reset

The testcase TC_paging_imsi_a_reset sends a paging request that
causes pagings on all cells. Then it performs a BSSMAP reset and
checks if the paging has stopped. In order to be sure that paging
requests from before the reset procedure are not mistakenly
detected as after-reset-pagings the RSL queue is cleared. However
this is only done for IPA_RSL[0], which means IPA_RSL[1] and
IPA_RSL[2] still contain old paging requests, which lets the test
fail.

- Clear IPA_RSL[1] and IPA_RSL[2] as well.
