ipa: Return -errno instead of -1 in ipa_send
Currently, the ipa_send function returns -1 in one execution branch to indicate an error and -EIO in another. This is not consistent and can lead to a misinterpretation of the error code, since -1 is -EPERM and in general, EPERM is not returned by write(2). This patch changes the return code to -errno instead of -1 for the case that write(2) fails for same reason. So -rc is always a sensible error value if there is a failure. Sponsored-by: On-Waves ehf
