46202aa823 isert: Fix null dereference in isert_cmnd allocation code 
In a state where the list isert_conn->tx_free_list is empty
(mostly under traffic), we might fail to receive a command from
the isert command pool. This will result in later null deref.

In this case, busy-wait until a command will be available (will
be freed by the receive context).

16a955ab7b scst: Move vfs_fsync() backports to a new header file 
This patch does not change any functionality but makes the SCST
source code easier to read. The intention is later on to move all
backported functions and macros from <scst.h> into <backport.h>.
