Fix PR 11034 by directly allocating per-cpu context data.
* translate.cxx (emit_common_header): Change type of 'contexts' to an
array of struct context pointers.
(emit_module_init): Allocate a context structure for each possible cpu.
Free each if an error occurs.
(emit_module_exit): Update contexts reference. Free each possible cpu's
context structure.
* tapsets.cxx (common_probe_entryfn_prologue): Use array instead of percpu
data for context structure.
