[PATCH] net/iavf: fix mbuf release bug for ARM Architecture

[Yang Ming]

This patch addresses a bug related to mbuf release in the ARM
architecture. The previous patch resolved the mbuf release issue
in a multi-process environment but was only applicable to the
x86 architecture, leaving ARM unaddressed.
This patch extends the fix to include the ARM architecture,
ensuring consistent behavior across both x86 and ARM platforms.
