Kernel: Fix usermode verification in ptrace with PT_SETREGS
When doing PT_SETREGS, we want to verify that the debugged thread is executing in usermode. b2f7ccf refactored things and flipped the relevant check around, which broke things that use PT_SETREGS (for example, stepping over breakpoints with sdb).
