Fix signed integer overflow
The operation "mRsmpInRear += framesRead;" would overflow
the 32-bit variables within 12 minutes for MSD HAL StreamIn IEC61937
MAT 2.0 framed streams (that generate 61440 bytes per 20 milliseconds).
Test: enable integer_overflow diagnostics, enable MSD HAL with IEC
MAT patch, wait for 12 minutes for UBSan crash, and check record
thread frame counts have exceeded 2^31.
