USB: musb: Fix array index out of bounds issue

This patch fixes the below array index out of bounds issue.

Buffer overflow, array index of 'aInfo' may be out of
bounds. Array 'aInfo' of size 78 may use index value(s) 6..84

The data stored in 'aInfo' array exceeds the array size of 78.

This patch increases the size of this array to hold the string
correctly without any memory corruption.

This issue was reported by Klockwork tool.
