ASoC: Fix WSA enumeration failure

In SDM450, WSA reset pin is shared for both WSA left
and right speakers. When reset pin toggled, both devices
enumerate and can be filled in any order in SWRM_DEV list.
But get_logical_address loops only once for first slave
addition and fails if the device entry is present at second
in SWRM_DEV list. Update logic of get_logical_address to
loop through max devices possible.
