[PATCH AUTOSEL 6.6 59/61] rocker: fix link status detection in rocker_carrier_init()

From: Dmitry Antipov <redacted>

[ Upstream commit e64285ff41bb7a934bd815bd38f31119be62ac37 ]

Since '1 << rocker_port->pport' may be undefined for port >= 32,
cast the left operand to 'unsigned long long' like it's done in
'rocker_port_set_enable()' above. Compile tested only.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
