isofs: shrink the name conversion buffer

isofs_readdir() and isofs_lookup() allocate 1024 bytes for the name
converters.  Now that get_rock_ridge_filename() and
get_joliet_filename() are told the buffer size, nothing writes beyond
JOLIET_NAME_MAX + 1 bytes: get_joliet_filename() is passed that size,
get_rock_ridge_filename() is passed NAME_MAX + 1, isofs_name_translate()
copies at most the 222 bytes of name a directory record can hold, and
get_acorn_filename() appends at most five bytes to that.

Allocate JOLIET_NAME_MAX + 1 bytes, matching what the Joliet callers
pass.

No functional change.
