Bjorn Andersson 2fae927c25 soc: qcom: mdt_loader: Deal with zero e_shentsize 
commit 25daf9af0a upstream.

Firmware that doesn't provide section headers leave both e_shentsize and
e_shnum 0, which obvious isn't compatible with the newly introduced
stricter checks.

Make the section-related checks conditional on either of these values
being non-zero.
