rpmsg: omx: return ENXIO in rpmsg_omx_write
The error code, ENXIO is used in rpmsg_omx driver to indicate
a terminal error on the remote processor side. This status is
maintained during the recovery of the remote processor, while
the cdev gets reinitialized/recreated.
The rpmsg_omx's write file operation is currently not returning
this error. This has been added now to have it behave in the
same way as the read file operation.
