[PATCH 4.14 077/229] wifi: p54: Fix an error handling path in p54spi_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 83781f0162d080fec7dcb911afd1bc2f5ad04471 ]

If an error occurs after a successful call to p54spi_request_firmware(), it
must be undone by a corresponding release_firmware() as already done in
the error handling path of p54spi_request_firmware() and in the .remove()
function.

Add the missing call in the error handling path and remove it from
p54spi_request_firmware() now that it is the responsibility of the caller
to release the firmware
