[ruby/io-console] Read errno before calling rb_io_path()
Possible fix for recent crashes seen on CI.
[BUG] rb_sys_fail_str(<STDIN>) - errno == 0
rb_io_path() calls rb_obj_dup(), which could call initialize_dup in Ruby
and clobber errno before rb_sys_fail_str() gets to read errno. So
save it out first.
(Using separate statements because order of evaluation in function call
list is unspecified, and order is important here.)
