e2e: do not use Failf() to abort tests in a go-routine (util)

There are several go-routines where Failf() is called, which will cause
a Golang panic inside the Ginko test framework. Instead of aborting the
go-routine, capture the error and check for failures once all
go-routines have finished.

The CephFS tests have been updated already, this changs only affects the
validatePVCClone() utility function.

Updates: #1359
