gdb: remove unnecessary NULL checks before xfree
I was inspired by a series of patches merged by Alan Modra in the other
projects, so I did the same in GDB with a bit of Coccinelle and grep.
This patch removes the unnecessary NULL checks before calls to xfree.
They are unnecessary because xfree already does a NULL check. Since
free is supposed to handle NULL values correctly, the NULL check in
xfree itself is also questionable, but I've left it there for now.
gdb/ChangeLog:
* coffread.c (patch_type): Remove NULL check before xfree.
* corefile.c (set_gnutarget): Likewise.
* cp-abi.c (set_cp_abi_as_auto_default): Likewise.
* exec.c (build_section_table): Likewise.
* remote.c (remote_target::pass_signals): Likewise.
* utils.c (n_spaces): Likewise.
* cli/cli-script.c (document_command): Likewise.
* i386-windows-tdep.c (core_process_module_section): Likewise.
* linux-fork.c (struct fork_info) <~fork_info>: Likewise.
