Summary
smb/server: fix potential null-ptr-deref of lease_ctx_info in smb2_open()
Details

In the Linux kernel, the following vulnerability has been resolved:

smb/server: fix potential null-ptr-deref of leasectxinfo in smb2_open()

null-ptr-deref will occur when (reqoplevel == SMB2OPLOCKLEVELLEASE) and parselease_state() return NULL.

Fix this by check if 'leasectxinfo' is NULL.

Additionally, remove the redundant parentheses in parsedurablehandle_context().
