FlexASIO attempts to check sample rate for disabled devices

Something I noticed in this log provided in #84:

Selecting input device
Device explicitly disabled in configuration
No input device, proceeding without input
…
--- ENTERING CONTEXT: canSampleRate()
Checking for sample rate: 44100
Checking if input supports this sample rate
CFlexASIO::OpenStream(inputEnabled = 1, outputEnabled = 0, sampleRate = 44100, framesPerBuffer = 0, callback = 00007FF9EEADB950, callbackUserData = 0000000000000000
Opening PortAudio stream with...
...input parameters: none
...output parameters: none
...sample rate: 44100 Hz
...frames per buffer: 0
...stream flags: 8 [PrimeOutputBuffersUsingStreamCallback]
...stream callback: 00007FF9EEADB950 (user data 0000000000000000)
Input does not support this sample rate: unable to open PortAudio stream: Invalid device

Obviously this is nonsensical - FlexASIO should not attempt to check a sample rate on a device that is not configured.

This is benign though and unlikely to cause any issues in practice, as FlexASIO just ignores the resulting error and moves on, as one would expect.

This is fixed in FlexASIO 1.6.
