staging/lustre: use 64-bit times for request times
All request timestamps and deadlines in lustre are recorded in time_t

In this patch, I'm converting them to time64_t and timespec64,
respectively. Unfortunately, this makes a relatively large patch,

breaking atomicity of the change.
Also unfortunately, this introduces two instances of div_u64_rem()

staging/rdma/hfi1: do not use u8 to store a 32-bit integer
hfi1_rc_hdrerr() stores the result of be32_to_cpu() into opcode, which
is a local variable declared as u8. Later this variable is used in a
24-bit logical right shift, which makes clang complains (when building
an allmodconfig kernel with LLVMLinux patches):
drivers/staging/rdma/hfi1/rc.c:2399:9: warning: shift count >= width
of type [-Wshift-count-overflow]
opcode >>= 24;
^ ~~
All of this lead to the point that opcode may have been designed to be
a 32-bit integer instead of an 8-bit one. Therefore make this variable
u32.
