Subject: [PATCH] drivers: scsi: qla2xxx: Remove redundant declaration in 'qla_gbl.h'

Remove 2 redundant extern inline functions: qla8044_set_qsnt_ready() and
qla8044_need_reset_handler(). At present, within upstream next kernel
source code, they are only used within "drivers/scsi/qla2xxx/qla_nx2.c".

The related error and warnings (with allmodconfig under tile):
