LE peripheral: fix a crash with unrecognized selector (iOS/macOS)

It's nice to re-use some generic functions, but it's not so if they are
actually not generic: data_from_bytearray returns NSData, not NSMutableData
and NSData (or whatever type they have under the hood) obviously does
not have replaceBytesInRange:withBytes: method and we get 'unrecognized
selector' exception  as a result.
