scsi: zfcp: Simplify workqueue allocation

Browse Source 
alloc_ordered_workqueue() accepts a format string and format arguments as
part of the call, so there is no need for the indirection of first using
snprintf() to print the name into an local array, and then passing that
array to the allocation call.

Also make the error-/non-error-case handling more canonical in that the
error case is tested in the 'if' that follows the allocation call, and
the default return value of the function is '0'.
