[PATCH v2] bus/fslmc: convert queue storage macros to inline functions

[Weijun Pan <wpan3636@gmail.com>]

From: Weijun Pan <wpan36@wisc.edu>

The queue storage allocation and free helpers are implemented as macros
which declare local variables in the caller scope. This can cause shadow
warnings when -Wshadow is enabled.

Convert them to static inline functions to avoid macro-local variable
scope issues without changing behavior.

Bugzilla ID: 1744
Fixes: 12d98eceb8ac ("bus/fslmc: enhance QBMAN DQ storage logic")
