Subject: [PATCH 4.19 189/243] usb: mtu3: fix dbginfo in qmu_tx_zlp_error_handler

From: YueHaibing <yuehaibing@...wei.com>

[ Upstream commit f770e3bc236ee954a3b4052bdf55739e26ee25db ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/usb/mtu3/mtu3_qmu.c: In function 'qmu_tx_zlp_error_handler':
drivers/usb/mtu3/mtu3_qmu.c:385:22: warning:
 variable 'req' set but not used [-Wunused-but-set-variable]

It seems dbginfo original intention is print 'req' other than 'mreq'
