The LinuxKPI linux_dma code calls PCTRIE_INSERT with a mutex held, but does not set M_NOWAIT when allocating nodes, leading to a potential panic. All of this code can handle an allocation failure here, so prefer an allocation failure to sleeping on memory. Also fix a related case where NOWAIT/WAITOK was not specified. In this case it's not clear whether sleeping is allowed so be conservative and assume not. There are a lot of other paths in this code that can fail due to a lack of memory anyway.
