Drop the proc lock around calls to the MD functions ptrace_single_step(),
ptrace_set_pc(), and cpu_ptrace() so that those functions are free to
acquire Giant, sleep, etc. We already do a PHOLD/PRELE around them so
that it is safe to sleep inside of these routines if necessary. This
allows ptrace() to be marked MP safe again as it no longer triggers lock
order reversals on Alpha.
