bdev/nvme: fix vendor_id formatting

Browse Source 
The printf # specifier adds 0x for %x values, but the field width then
includes the 0x part, so for example printf("%#04x", 0x1) prints "0x01"
rather than the intended "0x0001".

Rather than increasing the field width, just manually insert the 0x in
the format string and drop # for less confusion.
