[PATCH 6.1 0524/1146] wifi: brcmfmac: Fix error return code in brcmf_sdio_download_firmware()

From: Wang Yufen <wangyufen@huawei.com>

[ Upstream commit c2f2924bc7f9ea75ef8d95863e710168f8196256 ]

Fix to return a negative error code instead of 0 when
brcmf_chip_set_active() fails. In addition, change the return
value for brcmf_pcie_exit_download_state() to keep consistent.

Fixes: d380ebc9b6fb ("brcmfmac: rename chip download functions")
