Harrison Mutai b1f5309232 fix(debugfs): return negative value on error ...

The current implementation of buf_to_channel() returns 0 even on invalid
input, making it difficult for callers to distinguish between an error
and a successful zero-byte transfer.

Change the return behavior to return -1 for error conditions.
