Mikko Perttunen c711393bdf UPSTREAM: firmware: tegra: bpmp: Fix error paths in debugfs ...

Some error paths in mrq_debug_read and bpmp_debug_show would overwrite
the return error code with a subsequent call to mrq_debug_close.

Change the code to only change the error code if there was no prior
error.
