Subject: [PATCH] fix[osal]: Align MppMemPoolNode to 8-byte

Aligning MppMemPoolNode to 8-byte is aimed at avoiding alignment traps caused by compiler optimizations.

Log:
[   41.929204] Alignment trap: not handling instruction f44c6adf at [<a6f0aec4>]
[   41.929236] Unhandled fault: alignment exception (0x801) at 0xa6205cbc
