[dfsv2] fixup out-of-memory access (#8973)

This change addresses a potential out-of-memory access issue in the
devfs filesystem component. The issue arises when the `rt_malloc`
function allocates memory for a path string without accounting for
the null terminator, leading to undefined behavior.

As the manual documented:

> DESCRIPTION
>   The strlen() function calculates the length of the string pointed to
>   by s, excluding the terminating null byte ('\0').

To fix this, the memory allocation size was increased by one byte
to ensure space for the null terminator. This prevents potential
out-of-memory access and ensures proper string termination.
