lineedit: fix SEGV in isk, hexedit, ed, closes 11661
fdisk, hexedit and ed calls read_line_edit in libbb/lineedit.c with NULL as first argument. On line 2373 of lineedit.c of busybox version 1.29.3, state->hist_file is referenced without checking the state->flag. This causes segmentation fault on fdisk, hexedit and ed on ARM Cortex-A9. It somehow works on x86_64. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
