ui: fix crash on serial reset, during init
For ex, when resetting the xlnx-zcu102 machine: (lldb) bt * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x50) * frame #0: 0x10020a740 gd_vc_send_chars(vc=0x000000000) at gtk.c:1759:41 [opt] frame #1: 0x100636264 qemu_chr_fe_accept_input(be=<unavailable>) at char-fe.c:159:9 [opt] frame #2: 0x1000608e0 cadence_uart_reset_hold [inlined] uart_rx_reset(s=0x10810a960) at cadence_uart.c:158:5 [opt] frame #3: 0x1000608d4 cadence_uart_reset_hold(obj=0x10810a960) at cadence_uart.c:530:5 [opt] frame #4: 0x100580ab4 resettable_phase_hold(obj=0x10810a960, opaque=0x000000000, type=<unavailable>) at resettable.c:0 [opt] frame #5: 0x10057d1b0 bus_reset_child_foreach(obj=<unavailable>, cb=(resettable_phase_hold at resettable.c:162), opaque=0x000000000, type=RESET_TYPE_COLD) at bus.c:97:13 [opt] frame #6: 0x1005809f8 resettable_phase_hold [inlined] resettable_child_foreach(rc=0x000060000332d2c0, obj=0x0000600002c1c180, cb=<unavailable>, opaque=0x000000000, type=RESET_TYPE_COLD) at resettable.c:96:9 [opt] frame #7: 0x1005809d8 resettable_phase_hold(obj=0x0000600002c1c180, opaque=0x000000000, type=RESET_TYPE_COLD) at resettable.c:173:5 [opt] frame #8: 0x1005803a0 resettable_assert_reset(obj=0x0000600002c1c180, type=<unavailable>) at resettable.c:60:5 [opt] frame #9: 0x10058027c resettable_reset(obj=0x0000600002c1c180, type=RESET_TYPE_COLD) at resettable.c:45:5 [opt] While the chardev is created early, the VirtualConsole is associated after, during qemu_init_displays().
