wifi: mt76: mt7921: fix missing unwind goto in mt7921u_probe

Browse Source 
[ 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.
