The Multiple Message Capable field in the MSI Message Control register indicates how many vectors the device supports. This field is read-only, so cache it in msi_desc to avoid reading it repeatedly. Since we cache the extracted field (not the entire Message Control register), we can use msi_mask() instead of msi_capable_mask(), which is then unused, so remove it.
