elm_entry: prevents invalid cursor position updates

Summary:
sd->cursor_pos is updated in _entry_cursor_changed_signal_cb.
Generally, there is no problem.
But in some cases, before the _entry_cursor_changed_signal_cb is called
there is a situation in which cursor_pos is updated through _elm_entry_efl_ui_widget_theme_apply.

In this case,
before _entry_cursor_changed_signal_cb is called,
in _elm_entry_efl_ui_widget_theme_apply ()
cursor_pos = sd->cursor_pos; The wrong cursor_pos is set here.
Because it is the value before sd->cursor_pos is updated.
This causes an invalid cursor position when entering a key into the entry.

This patch prevents sd->cursor_pos from being updated with invalid values.
