[PATCH] net: mana: fix PCI_HYPERV dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The MANA driver causes a build failure in some configurations when
it selects an unavailable symbol:

WARNING: unmet direct dependencies detected for PCI_HYPERV
  Depends on [n]: PCI [=y] && X86_64 [=y] && HYPERV [=n] && PCI_MSI [=y] && PCI_MSI_IRQ_DOMAIN [=y] && SYSFS [=y]
  Selected by [y]:
  - MICROSOFT_MANA [=y] && NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_MICROSOFT [=y] && PCI_MSI [=y] && X86_64 [=y]
drivers/pci/controller/pci-hyperv.c: In function 'hv_irq_unmask':
drivers/pci/controller/pci-hyperv.c:1217:9: error: implicit declaration of function 'hv_set_msi_entry_from_desc' [-Werror=implicit-function-declaration]
 1217 |         hv_set_msi_entry_from_desc(&params->int_entry.msi_entry, msi_desc);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~

A PCI driver should never depend on a particular host bridge
implementation in the first place, but if we have this dependency
it's better to express it as a 'depends on' rather than 'select'.

 	  This driver supports Microsoft Azure Network Adapter (MANA).
