hwdb: fix dangling 'else' ambuguity
Imagine the following use of hwdb: if (condition_A) SD_HWDB_FOREACH_PROPERTY(hwdb, modalias, key, value) operation_A(key, value); else log_error("..."); This should work just fine, but but definitely does not what you would expect. Due to how SD_HWDB_FOREACH_PROPERTY is defined, the dangling 'else' is linked to the hidden 'if' statement in the macro instead of the outer 'if (condition_A)'. This is unexpected and really annoying to debug. Fix this by never leaving un-finished if-statements in SD_HWDB_FOREACH_PROPERTY(). We simply inverse the if() statement and explicitly add an 'else'-branch. This way, the statement is closed and all ambuguities are resolved.
