qemu: command: Handle FD passing commandline via qemuBuildBlockStorageSourceAttachDataCommandline

Copy the pointer to qemuFDPass into struct qemuBlockStorageSourceAttachData
so that it can be used from qemuBuildBlockStorageSourceAttachDataCommandline
rather than looping again in qemuBuildDiskSourceCommandLineFDs.
