Changed format specifiers to avoid compilation errors in arm 32-bit

**What I did**
This commit modifies various SWSS_LOG calls to use the correct format specifier

**Why I did it**
This fixes a build break when compiling for ARM 32-bit (armhf)

**How I verified it**
Successfully built the sonic-marvell-armhf.bin image
