net: b44: fix error return code in b44_init_one()

Browse Source 
[ Upstream commit 7b027c249da54f492699c43e26cba486cfd48035 ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 39a6f4bce6b4 ("b44: replace the ssb_dma API with the generic DMA API")
