usb: typec: Check for ops->exit instead of ops->enter in altmode_exit

[ Upstream commit b3c13e0353823603527792e803c897010e588376 ]

typec_altmode_exit checks if ops->enter is not NULL but then calls
ops->exit a few lines below. Fix that and check for the function
pointer it's about to call instead.
