vlr_ciph_result: fix use after free of imeisv
Define the struct vlr_ciph_result member .imeisv not as a char* but a char[] of
appropriate length, to avoid the need to point to external memory.
Thus fix a use-after-free in msc_cipher_mode_compl(), which defined the
imeisv[] buffer in a sub-scope within that function, so that the .imeisv
pointer was already invalid when fed to vlr_subscr_rx_ciph_res().
Did you notice that the commit summary rhymes?
