nvme-fc: Fix wrong return value in __nvme_fc_init_request()

Browse Source 
[ Upstream commit f34448cd0dc697723fb5f4118f8431d9233b370d ]

On an error exit path, a negative error code should be returned
instead of a positive return value.

Fixes: e399441de9115 ("nvme-fabrics: Add host support for FC transport")
