usb: typec: ucsi: correctly access opcode

hdr->opcode is __le32 type, use le32_to_cpu() to cast opcode
to integer in the switch..case statement to fix the following
sparse warnings:

drivers/usb/typec/ucsi/ucsi_glink.c:248:20: sparse: warning: restricted __le32 degrades to integer
drivers/usb/typec/ucsi/ucsi_glink.c:248:20: sparse: warning: restricted __le32 degrades to integer
drivers/usb/typec/ucsi/ucsi_glink.c:248:20: sparse: warning: restricted __le32 degrades to integer

No functional change.
