Junjie Mao f52a25db7e HV: ptdev: convert vectors in msi_info to unsigned integers
Vectors are unsigned integers now. This patch converts the vectors in struct
ptdev_msi_info to uint32_t so that all variables representing interrupt vectors
are aligned.

No other changes needed except the type declarators since the other functions
manipulating vectors already takes/returns uint32_t.
