iio: accel: kxcjk-1013: Fix possible memory leak in probe and remove

When ACPI type is ACPISMO8500, the data->dreadytrig will not be set, the memory allocated by iiotriggeredbuffer_setup() will not be freed, and cause memory leak as follows:

unreferenced object 0xffff888009551400 (size 512): comm "i2c-SMO8500-125", pid 911, jiffies 4294911787 (age 83.852s) hex dump (first 32 bytes): 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 20 e2 e5 c0 ff ff ff ff ........ ....... backtrace: [<0000000041ce75ee>] kmemcachealloctrace+0x16d/0x360 [<000000000aeb17b0>] iiokfifoallocate+0x41/0x130 [kfifobuf] [<000000004b40c1f5>] iiotriggeredbuffersetupext+0x2c/0x210 [industrialiotriggeredbuffer] [<000000004375b15f>] kxcjk1013probe+0x10c3/0x1d81 [kxcjk1013]

Fix it by remove data->dready_trig condition in probe and remove.
