KVM: x86: do not fail if software breakpoint has already been removed
If kvm_arch_remove_sw_breakpoint finds that a software breakpoint does not
have an INT3 instruction, it fails. This can happen if one sets a
software breakpoint in a kernel module and then reloads it. gdb then
thinks the breakpoint cannot be deleted and there is no way to add it
back.
