commit 0181944fe647cae18d545ac1167df3d15d393701 adds a
'extended_error_logging' global variable to qla2xxx which is defined by
qla4xxx too.
Trying to build both drivers results in the following error:

LD drivers/scsi/built-in.o
drivers/scsi/qla4xxx/built-in.o: In function
`qla4xxx_slave_configure':
drivers/scsi/qla4xxx/ql4_os.c:1433: multiple definition of
`extended_error_logging'
drivers/scsi/qla2xxx/built-in.o:drivers/scsi/qla2xxx/qla_os.c:2166:
first defined here
make[2]: *** [drivers/scsi/built-in.o] Error 1
make[1]: *** [drivers/scsi] Error 2
make: *** [drivers] Error 2

The following patch simply adds a qla2_ (qla4_ respectively) prefix to
the variable name.

Regards,
Frederik
