Remove unused parameter in maybe_software_singlestep

While working around, I noticed that the last parameter of
maybe_software_singlestep is never used.  This path removes
it.

Built on x86_64-linux-gnu and riscv64-linux-gnu.

gdb/ChangeLog:

	* infrun.c (maybe_software_singlestep): Remove unused PC
	parameter.
	(resume_1): Update calls to maybe_software_singlestep.
