msm: ipa: Fix buffer overflow issue

BugLink: https://bugs.launchpad.net/bugs/1931727



Currently during IPA_IOC_GET_PHERIPHERAL_EP_INFO ioctl we are not
returning for the invalid values of max_ep_pairs and ep_pair_size,
which is resulting in call of functions with invalid parameters.
So now changing the control when we receive unexpected values.
