    LinuxKPI: fix argument type to lkpi_pci_msi_desc_alloc()
    
    lkpi_pci_msi_desc_alloc() takes an unsigned int, not an int.
    While here make sure the prototype is visibile in interrupt.h as
    well before use to avoid -Wimplicit-function-declaration errors.
    
    Discovered while working on a wireless driver.
