cifs: Fix use-after-free in SMB2_write



There is a KASAN use-after-free:
BUG: KASAN: use-after-free in SMB2_write+0x1342/0x1580
Read of size 8 at addr ffff8880b6a8e450 by task ln/4196

Should not release the 'req' because it will use in the trace.

Fixes: eccb4422 ("smb3: Add ftrace tracepoints for improved SMB3 debugging")
