soc: qcom: mdt_loader: Extend check for split firmware
Some of the Qualcomm SM8450 firmware files are padded such that the
start of the first segment falls within the .mdt file but the segment to
be loaded is stored as a separate .bNN file.
Extend the condition to only attempt to read a segment inline if the
entire segment would be available.
