Kernel: Don't dispatch signals in Processor::enter_current()

Browse source 
Signal dispatch is already taken care of elsewhere, so there appears to
be no need for the hack in enter_current().

This also allows us to remove the Thread::m_in_block flag, simplifying
thread blocking logic somewhat.

Verified with the original repro for #4336 which this was meant to fix.
