common: spl: spl_dfu.c: Fix warning associated with PCI subclass_code
The subclass_code member of the pci_ep_header structure is a 1-byte
field. The macro PCI_CLASS_MEMORY_RAM is a concetation of baseclass_code
and subclass_code as follows:
PCI_BASE_CLASS_MEMORY: 0x05
Subclass Code for RAM: 0x00
PCI_CLASS_MEMORY_RAM: 0x0500
Hence, instead of extracting it via an implicity type conversion from int
to u8 which throws a warning, explicitly mask the bits to extract the
subclass_code.
