IB/uverbs: Fix validating mandatory attributes
Previously, if a method contained mandatory attributes in a namespace
that wasn't given by the user, these attributes weren't validated.
Fixing this by iterating over all specification namespaces.
Fixes: fac9658cabb9 ("IB/core: Add new ioctl interface")
