soc: qcom: mdt_loader: Fix error return values in mdt_header_valid()
commit 9f35ab0e53ccbea57bb9cbad8065e0406d516195 upstream.
This function is supposed to return true for valid headers and false for
invalid. In a couple places it returns -EINVAL instead which means the
invalid headers are counted as true. Change it to return false.
Fixes: 9f9967fed9d0 ("soc: qcom: mdt_loader: Ensure we don't read past the ELF header")
