nfs_main.c: add prctl(PR_SET_IO_FLUSHER,1) call to avoid kernel deadlocks
See
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=master&id=8d19f1c8e1937baf74e1962aae9f90fa3aeab463
Setting PR_SET_IO_FLUSHER prevents recursive allocation for user space
components that are in the I/O path. Otherwise a deadlock can occur when
device I/O needs to allocate memory but the allocation would require
device I/O to complete.
