Remove the code that set LOCK_PATTERN_VISIBLE to true the first time a
pattern was set, since LOCK_PATTERN_VISIBLE now defaults to true when
unset (ag/22912136). The explicit defaulting to true was only needed
before because the low-level default value was wrong.
Bug: 270013005
Test: Set a pattern. Verified that Keyguard uses visible pattern.
Disabled the "Make pattern visible" option in Settings. Verified
that Keyguard doesn't use visible pattern.
