UEK 4 RPMs like kernel-uek-4.14.35-2025.402.2.1.el7uek.x86_64 include a
backport of cpu_to_be32_array() and kvcalloc(). Hence disable the SCST
backports for these functions when building against UEK 4.

Use a workqueue for processing RDMA completions instead of creating one
kernel thread per RDMA channel. This change improves performance if the
number of RDMA channels is large by reducing the number of context
switches between kernel threads while processing RDMA completions. An
additional change is that srpt_set_ch_state() no longer wakes up the
RDMA completion context but that srpt_cm_rtu_recv() wakes up the RDMA
completion context instead.

- Return EOPNOTSUPP instead of ENOTSUPP to user space.
- Do not terminate macro definitions with a trailing semicolon.
- Do not initialize static variables to zero.

Apparently the RHEL 8.2 gcc compiler reports an error if
__attribute__((fallthrough)) is used outside a switch statement. Hence this
patch that converts some of these annotations back into comments.

Validate the $value argument of set functions with defined() instead of
length(). Append a newline to the end of $value before writing it into
a sysfs attribute to make sure something gets written if $value eq "".
