Revert "net: libwx: fix alloc msix vectors failed"

BugLink: https://bugs.launchpad.net/bugs/2089340

This reverts commit 69197dfc64007b5292cc960581548f41ccd44828.
commit 937d46ecc5 ("net: wangxun: add ethtool_ops for
channel number") changed NIC misc irq from most significant
bit to least significant bit, the former condition is not
required to apply this patch, because we only need to set
irq affinity for NIC queue irq vectors.
this patch is required after commit 937d46ecc5 ("net: wangxun:
add ethtool_ops for channel number") was applied, so this is only
relevant to 6.6.y branch.
