[ Upstream commit 0c08aaf873174c95e674cf21ffcd041c589d2e5b ]

ISL9305_MAX_REGULATOR is the last index used to access the init_data[]
array, so we need to add one to this last index to obtain the necessary
array size.

This fixes the following smatch error:

  drivers/regulator/isl9305.c:160 isl9305_i2c_probe() error: buffer overflow 'pdata->init_data' 3 <= 3
