CVE-2026-64381

smb: client: Fix next buffer leak in receive_encrypted_standard()

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

smb: client: Fix next buffer leak in receive_encrypted_standard()

receive_encrypted_standard() allocates next_buffer before checking
whether the number of compound PDUs already reached MAX_COMPOUND. If
the limit check fails, the function returns immediately and the newly
allocated next_buffer is not assigned to server->smallbuf/server->bigbuf,
making it leaked.

Move the MAX_COMPOUND check before allocating next_buffer.
