drivers: misc: ti-st: fix potential race if st_kim_start fails
If st_kim_start() fails registered protocols should be removed. This is done by calling st_reg_complete(), which as comment states is called with spin lock held. But in st_register() when st_kim_start fails it is called without holding spin lock, creating possibility of concurrent access to st_gdata data members. Hold spin lock while calling st_reg_complete if st_kim_start() fails.
