Subject: [PATCH] wifi: mt76: mt7921: fix missing unwind goto in
`mt7921u_probe`
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 5c47cdebbaeb7724df6f9f46917c93e53f791547
[ Upstream commit 5c47cdebbaeb7724df6f9f46917c93e53f791547 ]
`mt7921u_dma_init` can only return zero or negative number according to its
definition. When it returns non-zero number, there exists an error and this
function should handle this error rather than return directly.
