MIPS: uprobes: Restore thread.trap_nr

Browse Source 
thread.trap_nr is saved in arch_uprobe_pre_xol(), it should be restored
in arch_uprobe_{post,abort}_xol() accordingly, actually it was only done
in the post function, just do it in the abort function too, this change
is similar with x86 and powerpc.
