IPA: drop implicit_section again
As mentioned in the PR, since 4656461585bfd0b9 implicit_section
was not set to false when set_section was called with the argument
equal to NULL.
gcc/ChangeLog:
PR ipa/98057
* symtab.c (symtab_node::set_section_for_node): Drop
implicit_section if x_section is NULL.
gcc/testsuite/ChangeLog:
PR ipa/98057
* g++.dg/ipa/pr98057.C: New test.
