remoteproc: qcom: mdt_loader: Use signed type for offset
In the transition from using rproc_da_to_va(), the type of the load
offset became unsigned. This causes the subsequent check to let negative
values less than p_memsz + mem_size through and we write outside of the
buffer.
Change the type back to a signed value to catch this.
Fixes: 7f0dd07a9b29 ("remoteproc: qcom: mdt_loader: Refactor MDT loader")
Fixes: e7fd25226295 ("remoteproc: qcom: q6v5: Decouple driver from MDT loader")
