regulator: max77693: Remove NULL test for rmatch[i].init_data

The implementation in of_regulator_match() already ensures match->init_data is
not NULL for all matched cases if the return value of of_regulator_match() > 0.

Thus remove NULL test for rmatch[i].init_data.

This patch also fixes the condition for loop iteration.
The for loop should iterate "matched" times rather than ARRAY_SIZE(regulators)
because we only allocate "matched" number of entries for rdata.
Though in most cases, "matched" == ARRAY_SIZE(regulators).
