wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init()

Browse source

[ Upstream commit efb95439c1 ]

devm_ioremap() returns NULL on error. Currently, mt7915_mmio_wed_init()
does not check for this case, which results in a NULL pointer
dereference.

Prevent null pointer dereference in mt7915_mmio_wed_init().
