proc.c: assume rb_iseq_location_t::first_lineno is always a Fixnum

Do not check for the value of rb_iseq_constant_body::line_info_table as
it is no longer related. The checks seem to be the remains from the day
before the dedicated 'first_lineno' field was introduced. Remove them.

Note, rb_iseq_constant_body::line_info_table can be NULL only when the
iseq does not contain any instructions that originate from Ruby code,
for example, an iseq created with 'proc {}' under a non-default compile
options where trace instructions are disabled.
