Use temporary fd instead of global fd for getattr/setattr/LOCKT
Some use cases have shown issues with opening a global file descriptor
for getattr/setattr which then remains open until the LRU thread gets
around to closing it. This can result in a lot of open fd, or preventing
Samba clients from opening the file.
This patch simply prevents opening the global file descriptor when the
FSAL_O_ANY openflags mode is selected, instead if the global file
descriptor is NOT open, it opens a temporary file descriptor. If the
global file descriptor IS open, it will still be utilized, so we avoid
extraneous open for getattr that occurs amidst anonymous I/O.
