[PATCH] iio: adc: ti-ads7138: explicitly include <linux/slab.h>

[Giorgi Tchankvetadze]

ti-ads7138.c uses kmalloc() and kfree(), which are provided by
linux/slab.h, but does not include that header directly.
The driver currently gets these declarations through linux/i2c.h.
Include linux/slab.h explicitly instead of relying on the transitive
include.
