Fix MRI mode testsuite failures

[Alan Modra]

These fails were introduced by git commit 2469b3c584 with the
inroduction of "input_from_string":
m68k-linux  FAIL: MRI structured for
m68k-linux  FAIL: MRI structured if
m68k-linux  FAIL: MRI structured repeat
m68k-linux  FAIL: MRI structured while

Since the m68k parser called expression() without setting
input_from_string, get_symbol_name rejected FAKE_LABEL_CHAR in names.

	* config/m68k-parse.y (yylex): Use temp_ilp and restore_ilp.
