md: Fix compilation warning
Remove the if statement around the calls to sysfs_link_rdev() to avoid
the compilation warnings:
warning: suggest braces around empty body in an ‘if’ statement
when compiling with W=1. For the call to sysfs_create_link() generating
the same warning, use the err variable to store the function result,
avoiding triggering another warning as the function is declared
as 'warn_unused_result'.
