Bjorn Andersson 6167d72fe5 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.

Fixes: 9f9967fed9 ("soc: qcom: mdt_loader: Ensure we don't read past the ELF header")
