[PATCH OLK-6.6] smb: client: fix wrong index reference in smb2_compound_op()

From: Sang-Heon Jeon <ekffu200098(a)gmail.com> stable inclusion from stable-v6.6.109 commit ba7bcfd52c66dd1c2dfa5142aca7e4a70b62dfa5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID228Z CVE: CVE-2025-39975 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fbe2dc6a9c7318f7263f5e4d50f6272b931c5756 ] In smb2_compound_op(), the loop that processes each command's response uses wrong indices when accessing response bufferes. This incorrect indexing leads to improper handling of command results. Also, if incorrectly computed index is greather than or equal to MAX_COMPOUND, it can cause out-of-bounds accesses.
