regmap: fix the kerneldoc for regmap_test_bits()
The kerneldoc comment for regmap_test_bits() says that it returns -1 on
regmap_read() failure. This is not true - it will propagate the error
code returned by regmap_read(). Fix it.
Fixes: aa2ff9dbaedd ("regmap: provide helpers for simple bit operations")
