PCI/MSI: Check kmalloc() return value, fix leak of name

Coverity reported that I forgot to check the return value of kmalloc() when
creating the MSI attribute name, so fix that up and properly free it if
there is an error when allocating the msi_dev_attr variable.

Found by Coverity (CID 1163315 and 1163316).

Fixes: 1c51b50c2995 ("PCI/MSI: Export MSI mode using attributes, not kobjects")
