Subject: [2.6 patch] SCSI qla2xxx: fix inline compile errors

Trying to compile the SCSI qla2xxx driver in 2.6.8-rc1-mm1 using gcc 3.4 
results in the following compile errors:

make[3]: *** [drivers/scsi/qla2xxx/qla_rscn.o] Error 1

<--  snip  -->


The patch below moves some inlined functions above the place where they
are called the first time.

An alternative approach would be to remove the inlines.
