pcmcia: Add error handling for add_interval() in do_validate_mem()
[ Upstream commit 4a81f78caa53e0633cf311ca1526377d9bff7479 ]
In the do_validate_mem(), the call to add_interval() does not
handle errors. If kmalloc() fails in add_interval(), it could
result in a null pointer being inserted into the linked list,
leading to illegal memory access when sub_interval() is called
next.
This patch adds an error handling for the add_interval(). If
add_interval() returns an error, the function will return early
with the error code.
