s390: avoid always-true comparison in s390_pci_generate_fid()
Coverity points out that the comparison "fid <= ZPCI_MAX_FID" in s390_pci_generate_fid() is always true (because fid is 32 bits and ZPCI_MAX_FID is 0xffffffff). This isn't a bug because the real loop termination condition is expressed later via an "if (...) break;" inside the loop, but it is a bit odd. Rephrase the loop to avoid the unnecessary duplicate-but-never-true conditional.
