pdch: fix packet_paging_request(): properly print paging MI

This problem problem was discovered by the Undefined Behavior Sanitizer:

  pdch.cpp:210:4: runtime error: load of misaligned address
                  0x60c00002abf2 for type 'uint32_t',
                  which requires 4 byte alignment

Do not convert TMSI to number, use osmo_mi_name() from libosmocore.
Also use this function to print other MI types (IMSI or IMEISV).
