[ 54/61] remoteproc: fix missing fault indication in error-path

[Greg KH]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sjur Brændeland <sjur.brandeland@xxxxxxxxxxxxxx>

commit 30338cf09f82523d8747670f7363cc8af347c79f upstream.

If rproc_find_rsc_table() fails, rproc_fw_boot() must set
return-value before jumping to clean_up label. Otherwise no
error value is returned.
