[PATCH] net: wwan: iosm: use int type to store negative error codes

[Qianfeng Rong]

The 'ret' variable in ipc_pcie_resources_request() either stores '-EBUSY'
directly or holds returns from pci_request_regions() and ipc_acquire_irq().
Storing negative error codes in u32 causes no runtime issues but is
stylistically inconsistent and very ugly.  Change 'ret' from u32 to int
type - this has no runtime impact.
