Zhang Xiaoxu 53b9b1201e Input: raydium_ts_i2c - fix memory leak in raydium_i2c_send() 
commit 8c9a59939d upstream.

There is a kmemleak when test the raydium_i2c_ts with bpf mock device:

  unreferenced object 0xffff88812d3675a0 (size 8):

      [<00000000ffec4177>] of_i2c_notify+0x100/0x160

After BANK_SWITCH command from i2c BUS, no matter success or error
happened, the tx_buf should be freed.

Fixes: 3b384bd6c3 ("Input: raydium_ts_i2c - do not split tx transactions")
