[PATCH] soc: qcom: mdt_loader: Fix error return values in mdt_header_valid()

[Dan Carpenter <dan.carpenter@linaro.org>]

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")
