There is race condition on PM defer deactive and PM active where
the PM active triggered by new NAPI scheduling would be accidently
unvoted by PM defer deactive after last NAPI completion. This
is causing the NoC error on packet handling due to no clock.
The fix here is to using ACTIVE_CLIENT_NO_BLOCK for clock voting
and still use PM handle for BW voting so that we would have
reference count to make sure this unexpected devote not happens.

Currently during RMNET_IOCTL_GET_MTU and RMNET_IOCTL_SET_MTU ioctls
we can recieve not null terminated string for if_name which was
resulting in string out of bound error while accessing the if_name.
Now adding null character at the end of string to prevent access
beyond its size.

Use read memory barrier before reading event from event ring.
Since ring is shared resource between IPA h/w and IPA driver
dma_rmb is used to ensure memory write is complete before
reading from driver.

IPA HW tries to prefetch 128 Bytes of additional memory when
