Summary:
- In case of SMP and ADDRENV, allocate current group for each cpu
- g_pid_current holds pid of the group and uses for addrenv switching
- allocate g_group_current for each cpu in stead of g_pid_current
- g_group_current is the array that pointed to the current task_group_s struct
Impact:
- ADDRENV=y and SMP=y
Testing:
- sabre-6quad:smp w/ qemu
- sabre-6quad:knsh w/ qemu
- sabre-6quad:knsh_smp w/ qemu (WIP)
